Poly-electrolytes
are polymers with repeating units of stationary charges.
HemogloBind™ is derived from insoluble elastomeric
poly-electrolytes that bind proteins through an empirically derived
chemistry combining elements of polymer composition, and
cross-linking architecture. As with bio-polymers like DNA and
Heparin, governing their reactivity is the spatial presentation of
electrostatic groups along a flexible polymer chain.
HemogloBind™
does not cross react with most common serum components, making it an
excellent tool in numerous applications. These include analytical
protocols where optical interference is problematic. Hemoglobin
variants, as in thalassemia, bind with differential affinity towards
HemogloBind™, though this has not been fully evaluated. For
purification and/or analysis of hemoglobin, a modest elevation in pH
will facilitate desorption from the polymer.

Craig, J. R., et al. "A comparison of the anatomical and gastrointestinal functional development between gilt and sow progeny around birth and weaning." Journal of animal science (2019).
Biotech Support Group reports on an article describing the simplicity and efficiency of their hemoglobin depletion technology for improving ELISA analysis from hemolyzed pig serum. Gilt progeny (GP) often have restricted growth performance and health status in comparison to sow progeny (SP) from birth. To better understand underlying mechanisms, the study aimed to compare differences in growth and development between GP and SP in the first 24 h after birth and in the peri-weaning period. Because serum samples were quite hemolysed after collection and processing, it became necessary to use HemogloBind™ to allow for better detection of IgG by ELISA. The article states “As per the manufacturer’s instructions, 250 μL of Hemoglobind™ was added to 250 μL of hemolyzed serum, vortexed for 30 s before mixing via inversion for 10 min, and then centrifuged at 6,000 g for 2 min at 4°C. Purified serum was then aspirated and assessed in duplicate for IgG concentration … using a commercial ELISA kit (Bethyl Laboratories, Montgomery TX, USA).” The authors conclude their findings suggest that the early development of GP may be delayed compared to SP, and that a number of the anatomical differences between GP and SP that exist after birth are also present at weaning.

Nguyen, Anthony T., et al. "UBE2O remodels the proteome during terminal erythroid differentiation." Science 357.6350 (2017): eaan0218.
Biotech Support Group reports on a Science article describing the simplicity and efficiency of their hemoglobin depletion technology for improving LC-MS analysis from lysed reticulocytes.The mechanisms that drive reticulocyte transition to red blood cell in terminally differentiating cells remain largely unclear. During reticulocyte maturation, the proteome is remodeled through the programmed elimination of most generic constituents of the cell, in parallel with abundant synthesis of hemoglobin. The study used multiplexed quantitative proteomics to identify candidate substrates of UBE2O, an E2 (ubiquitin-conjugating) enzyme, in an unbiased and global manner. Because of the overly abundant presence of Hemoglobin, selective depletion of Hemoglobin was necessary. The article states “Reticulocytes were lysed by vortexing for 5 minutes at room temperature… An additional 10 bed vol of Hemoglobind™ suspension was added to the samples, which were then vortexed for another 10 min at room temperature followed by 4 min of centrifugation at 10000 x g. The supernatants, which contain hemoglobin-depleted sample, were … processed for TMT quantification.”. The authors concluded that the ubiquitin-proteasome system is not simply amplified during erythroid maturation, but suggest instead that it is broadly reconfigured to promote remodeling of the reticulocyte proteome. “The large amount of hemoglobin in reticulocytes presents a special challenge for LC-MS quantitative analysis. Here is another article demonstrating that HemogloBind™ can drastically reduce the interference associated with large concentrations of hemoglobin, without compromising the recovery and analysis of the underlying proteome.” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
Hemocyte fractions
O’Connell, Grant C., et al. "Monocyte-lymphocyte cross-communication via soluble CD163 directly links innate immune system activation and adaptive immune system suppression following ischemic stroke." Scientific reports 7.1 (2017): 12940
The purpose of this study was to investigate CD163 as a possible effector of stroke-induced adaptive immune system suppression as this is a scavenger receptor expressed on innate immune cell populations. A soluble peptide with lympho-inhibitory properties can be shed from the plasma membrane via the metalloprotease ADAM17. The article states “Total hemocyte fractions were thawed, mixed with NP-40 lysis buffer (Thermo Fisher) at a 1 to 1 ratio, and depleted of hemoglobin via the HemogloBind hemoglobin removal kit (Biotech Support Group, Monmouth Junction, NJ)… ADAM17 activity was measured in 200 ug of total hemocyte lysate”. The authors provide novel evidence that the innate immune system employs protective mechanisms aimed at mitigating the risk of post-stroke autoimmune complications, and that CD163 is a key mediator of this phenomenon..
Perfusates Laing, Richard W., et al. "The use of an acellular oxygen carrier in a human liver model of normothermic machine perfusion." Transplantation 101.11 (2017): 2746. The
authors present the first experience of using an acellular
hemoglobin-based oxygen carrier (HBOC) Hemopure in a human model of
Normothermic machine perfusion of the liver (NMP-L). This is a novel
technique that preserves liver grafts under near-physiological
conditions while maintaining their normal metabolic activity. The
article states “All perfusates underwent haemoglobin depletion
using Hemoglobind (BioTech Support Group LLC, Monmouth Junction, NJ)
as per the manufacturer’s instructions, except using a 1:8 ratio to
ensure removal of all free haemoglobin. Perfusate levels of 8-OH-dG
were quantified using a competitive ELISA (Abcam) as per the
manufacturers protocol” .The authors conclusion is that Hemopure
can be used as an alternative oxygen carrier to packed red cells in
NMP-L perfusion fluid. Hemolysate
Dasauni, Pushpanjali, et al. "Refractive index of blood is a potential qualitative indicator of hemoglobin disorder in humans." Journal of Proteins & Proteomics 9.3 (2018) Qualitative defects of codons in hemoglobin chains causes hemoglobin disorders such as hemoglobin variants, thalassemia and sickle cell disease. Authors wanted to estimate the concentration of hemoglobin by measuring refractive index and find differences in the refractive index of blood samples. Blood was centrifuged to separate plasma. Hemoglobin is separated from hemolysate using Hemoglobind™ reagent. The refractive index was evaluated in whole blood, plasma, hemolysate and pure Hb.
Cell lysates of reticulocytes
Junqueira, Caroline, et al. "Cytotoxic CD8+ T cells recognize and kill Plasmodium vivax–infected reticulocytes." Nature medicine (2018): 1.
Biotech Support Group reports on a recent research article describing the simplicity and efficiency of their hemoglobin depletion technology for improving Western blot analysis from reticulocytes.The Malaria parasite Plasmodium vivax causes approximately 100 million clinical cases yearly. The basis of protective immunity is poorly understood yet thought to be mediated by antibodies. The authors hypothesized that CD8+ T Cells in patient with P. vivax malaria might become activated by recognizing P. vivax-infected reticulocytes (iRetics), causing them to degranulate. To evaluate the expression levels of proteins involved in antigen presentation in reticulocytes by Western blot, the article states “Cell lysates of reticulocytes…were analyzed by immunoblot…after hemoglobin removal using HemogloBind™ (Biotech Support Group)”. The authors conclude that P. vivax renders reticulocytes granulysin-susceptible and that this unexpected T Cell defense might be mobilized to improve vaccines. “The large amount of hemoglobin in whole blood presents a special challenge for quantitative Western blot analysis. Here is another article demonstrating that HemogloBind™ can reduce the interference associated with large concentrations of hemoglobin, without compromising the recovery and analysis of the protein of interest.” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
Whole blood aliquots

Biotech
Support Group reports on a recent research article describing the
describing the simplicity and efficiency of their hemoglobin
depletion technology for improving Western blot analysis from whole
blood.The authors studied Methylglyoxal production known to increase
in diabetic patients. Methylglyoxal is efficiently detoxified by
enzyme glyoxalase 1 (GLO1). The aim was to study the effect of
diabetic and chronic kidney disease milieu on (a) GLO1 gene
expression in peripheral blood mononuclear cells; (b) GLO1 protein
levels in whole blood; and (c) GLO1 activity in RBCs in vivo in
diabetic vs. non-diabetic subjects with normal or slightly reduced
vs. considerably reduced renal function (CKD1-2 vs. CKD3-4).
To

he
article states “For protein isolation, whole blood aliquots were
lysed with water and haemoglobin was removed using HemogloBind™
(Biotech Support Group, Monmouth Junction, NJ, USA) according to the
manufacturer’s instructions…
”.
The article concludes that chronic kidney disease in advanced stages
has prevailing and suppressive effects compared to hyperglycaemia.
Chronic kidney disease decreases GLO1 gene expression and protein
levels (together with diabetes) without concomitant changes of GLO1
activity.“The large amount of hemoglobin in whole blood presents a
special challenge for quantitative Western blot analysis. Here is
another article demonstrating that HemogloBind™ can reduce the
interference associated with large concentrations of hemoglobin,
without compromising the recovery and analysis of the protein of

O'Connell, Grant C., et al. "Monocyte-Lymphocyte Cross-Communication Via Soluble CD163 Directly Links Innate Immune System Activation And Adaptive Immune System Suppression Following Ischemic Stroke." bioRxiv (2017): 144063.
CD163 is linked to peripheral immune response in stroke via the circulating levels of damage associated molecules, hormones and proinflammatory cytokines. Stroke can alter serum neutrophil ADAM17 dependent sCD163 production and lymphocyte proliferation. An ADAM17 activity assay was performed from hemoglobin depleted total hemocyte lysates. Measurement of protein concentrations of hemoglobin depleted total hemocyte lysates and cell culture lysates was obtained by a DC-protein assay.

This study considers that therapeutic strategies targeting cancer-derived extracellular vesicles (EVs) hold
great promise because of the possibility they reposition microenvironments to accommodate metastasis. The researchers report on a novel strategy of therapeutic antibody treatment to target cancer-derived EVs and inhibit the metastasis of breast cancer in a mouse model. The article states “Hemoglobin was accumulated with HemogloBind beads (Biotech support group, Monmouth Junction NJ, USA) followed by 0.22 μm filtration. Then, the EVs in the sera were concentrated by ultracentrifugation…”. The authors conclude that therapeutic antibody administration effectively suppresses EV-triggered metastasis and that the elimination of cancer-exosome derived EVs could be a novel strategy for therapy
Bronchoalveolar lavage fluid (BALF)

Bitterman, David H. Ingbar, Chris H. Wendt. Proteome Profiling in Lung Injury after Hematopoietic Stem Cell Transplantation. Biology of Blood and Marrow Transplantation 22 (2016) 1383-1390.
The authors consider pulmonary complications due to infection and idiopathic pneumonia syndrome (IPS) in hematopoietic stem cell transplant (HSCT) recipients. For this, a proteomic characterization of global bronchoalveolar lavage fluid (BALF) was studied to identify proteins and pathways that differentiate IPS from infectious lung injury after HSCT. Because the BALF samples appeared tinged with blood, the authors tested HemogloBind™ to determine whether the removal of hemoglobin (in addition to high-abundance proteins) would improve the depth of coverage. The article states “Hemoglobin removal improved protein identification to 845 proteins at 1% global FDR compared with 496 proteins with high-abundance protein depletion alone”. The authors conclude that the protein expression differences provide insights into mechanisms activated in lung injury and suggest potential therapeutic targets to augment lung repair.

Chalásová, Katarína, et al. "Transketolase Activity but not Thiamine Membrane Transport Change in Response to Hyperglycaemia and Kidney Dysfunction." Experimental and Clinical Endocrinology & Diabetes (2017).
Biotech Support Group reports on a recent research article describing the simplicity and efficiency of their hemoglobin depletion technology for improving western blot analysis from whole blood protein. Diabetic kidney disease, a common complication of both type 1 and type 2 diabetes, is associated with significant morbidity and mortality, and represents the most common cause of chronic kidney disease. The study hypothesized that protective pentose phosphate pathway action in diabetes might be compromised by limited intracellular availability of an active transketolase cofactor thiamine diphosphate (TDP). To evaluate the levels of thiamine tranporter proteins in whole blood, the article states “For protein isolation, whole blood aliquots were lysed with water and haemoglobin was removed using HemogloBind™ (Biotech Support Group) according to manufacturer’s instructions…”. The article concludes that both in vitro and human experiments showed decrease or unchanged expression, respectively, of thiamine transporters induced by hyperglycaemia while transketolase activity in parallel with intracellular TDP was increased in chronic kidney disease patients with or without diabetes.
Lahut, Suna, et al. "Blood RNA biomarkers in prodromal PARK4 and REM sleep behavior disorder show role of complexin-1 loss for risk of Parkinson's disease." Disease Models & Mechanisms (2017): dmm-028035
Biotech Support Group reports on a recent research article describing the simplicity and efficiency of their hemoglobin depletion technology for improving the signal from whole blood protein immunoblot analysis. In this study, Parkinson’s disease progression is investigated through the accumulation and aggregation of the lipid-binding SNARE complex component alpha-synuclein (SNCA) which underlies vulnerability and defines its stages. The authors studied blood samples from a new large pedigree with SNCA gene duplication (PARK4 mutation), to identify effects of SNCA gain-of-function as potential disease biomarkers. The article states “For protein extraction from the EDTA tubes, 300 μl blood were lysed with equal amount of 1% SDS-RIPA buffer [50 mM Tris-HCl (pH 8.0), 150 mM NaCl, 1 mM EDTA, 1 mM EGTA, 1% Igepal CA-630 (Sigma), 0.5% sodium deoxycholate, 0.1% SDS, 1 mM PMSF and one tablet Complete Protease Inhibitor Cocktail (Roche)] and sonicated for 10 sec. The blood lysates were rotated at 4 °C for 30 min and centrifuged at 4 °C for 30 min. The supernatants were depleted in hemoglobin content using a commercial kit (HemogloBind, Biotech) following the manufacturer’s instructions”. After hemoglobin depletion, immunoblot analysis identified that PARK4 blood showed upregulation of alpha-synuclein monomer, with no high molecular weight aggregates. “Because of the large amount of hemoglobin in whole blood, its very exciting to see that HemogloBind™ can reduce the presence of hemoglobin sufficient for such precise immunoblot analysis.” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.

Two of BSG products, NRicher™ 6 and HemogloBind™, were able to contribute to this rigorous examination of protein complexes. When our products were used as a pretreatment step in the overall workflow, about twice the number of observations and annotations became possible. This further validates that the sub-proteome bias characteristics of NRicher™ 6 can simplify complex proteomes into less complex sub-proteomes with efficiencies suitable for deep functional proteome characterization. Furthermore, this study demonstrated the importance of a key feature implicit to all of our products; that is the maintenance of functional and structural integrity after separations. Without that particular feature, these additional observations would not have been possible.

A research article by authors Rubio-Navarro, Alfonso, et al in the journal International Journal of Cardiology (http://www.internationaljournalofcardiology.com/article/S0167-5273(15)30284-9/fulltext) cites Biotech Support Group’s HemogloBind™ sample preparation reagent to deplete hemoglobin (Hb) from conditioned medium from healthy aortas or abdominal aortic aneurysm. The article states:"Conditioned mediums from AAA were incubated with HemogloBind™ reagent for hemoglobin depletion"
In brief, authors describe high infiltration of CD163 monocytes surrounding micro-vesicles, low expression of CD14+ & CD16- monocytes and high CD163 mRNA/protein expression is a feature of abdominal aortic aneurysm (AAA) molecular pathology. Healthy aorta conditioned medium or complete or hemoglobin-depleted conditioned medium from abdominal aortic aneurysm were mixed with M-CSF macrophages to track CD163 and HLA-DR expression or hemoglobin uptake.
“We are pleased with this data on abdominal aortic aneuryism & hemoglobin proteomics. HemogloBind™ minimizes hemoglobin interference from blood samples and allows research on cardiovascular pathology” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.

A research article in the journal Analyst (
http://pubs.rsc.org/en/content/articlelanding/2015/an/c5an00345h) cites Biotech Support Group’s HemogloBind™ sample preparation reagent to deplete hemoglobin (Hb) from whole blood samples containing glutathione to minimize interference from Hb in GSH fractions. Using a resorufin-acrylate fluorescent probe, GSH is quantitated in deproteinzed blood plasma and whole blood samples.
The article states:
"Apart from dilution, Hb can be removed using a commercial product, HemogloBind™, which can isolate and remove up to 90% of blood Hb." Glutathione (GSH) is an antioxidant involved on nitric oxide regulation, covalent hemoglobin binding, DNA binding, leukotriene synthesis, protein synthesis and sepsis pathways. GSH is elevated in cancer tissues and proper minimally invasive GSH sample preparation from dried blood samples (DBS) allows research on neurodegenerative diseases, chronic respiratory diseases and diabetes.

"Assessing the therapeutic efficacy of oxime therapies against percutaneous organophosphorus pesticide and nerve agent challenges in the Hartley guinea pig."The Journal of Toxicological Sciences 40, no. 6 (2015): 759-775.
Acetylcholine is an essential neurotransmitter, and inhibitors of cholinesterases(ChEs) are potent toxins. A primary component of anti-organophosphorus therapy is an oxime reactivator to rescue inhibited acetylcholinesterases. For this, clinical signs of toxicity can be measured from blood cholinesterase [Acetylcholinesterase (AChE) and butyrylcholinesterase (BChE)] activity utilizing a modified Ellman's method. Biotech Support Group’s unique solid-phase polymer for hemoglobin depletion, was used for pretreatment. The article states “Briefly, whole blood samples were treated with HemogloBind™ which interferes with the ChE activity assay due to spectral overlap.”

The article states “Whole blood samples were processed and analyzed as described by McGarry et al.10 Briefly, whole blood samples were treated with HemogloBind to remove hemoglobin, which interferes with the ChE activity assay due to spectral overlap. To prepare the HemogloBind treated blood samples for ChE activity analysis, samples were diluted 2-fold in assay buffer (1 PBS). Subsequently, samples were diluted an additional 2-fold into the test plate by adding 100 mL of sample to a total volume of 200 mL in each well of a 96-well plate. Cholinesterase activity was assessed using a spectrophotometric assay conducted in a manner similar to Ellman et al,11 as described in the in vitro reactivation section above. The relative AChE activity level for each animal (RAAChE) was defined as the ATC turnover rate in the terminal blood sample divided by that in the same animal’s baseline blood sample. A similar calculation was performed using butyrylthiocholine (BTC) turnover rates to determine RABChE.”

Erythrocyte proteins are highly O-GlcNAcylated. In individual with pre-diabetes and diabetes, the level of O-GlcNAcase expressed significantly increases. From serum samples, erythrocyte proteins were extracted and hemoglobin was depleted followed by sonication and centrifugation. From the red blood cell lysates hemoglobin is efficiently depleted using HemogloBind™ from Biotech Support Group. Because HemogloBind™ is engineered for a high degree of selectivity and does not cross react with most common serum components, subsequent analysis of O-GlcNAcylation process in erythrocyte proteins is done by Western blotting using an O-GlcNAc specific antibody. Finally, the study of O-GlcNAcase allows for developing, validating, and qualifying biological markers that are compared with the level of A1C.

Red Blood Cells(RBC)/Forensic Research
Danielson, Phillip B. "Isolation of Highly Specific Protein Markers for the Identification of Biological Stains: Adapting Comparative Proteomics to Forensics." (2011).
Biotech Support Group reports on a technical report prepared by the U.S. Department of Justice. The central goal of the project was to isolate and identify candidate protein biomarkers that are highly specific to individual types of biological stains of forensic utility (i.e., saliva, semen, peripheral blood, menstrual blood, vaginal secretions, and urine).
The report is entitled “Isolation of Highly Specific Protein Markers for the Identification of Biological Stains:Adapting Comparative Proteomics to Forensics". The National Criminal Justice Reference Service (NCJRS) has made this federally funded grant final report available electronically at: https://www.ncjrs.gov/App/Publications/abstract.aspx?ID=258706 The report states:
“Serum obtained from menstrual blood samples was typically contaminated with erythrocyte cellular components due to the lysing of fragile red blood cells that are abundant in the endometrial lining during menses. As hemoglobin comprises 32-36% of all the proteins found in red blood cells the serum from menstrual blood samples contained large quantities of hemoglobin which served to mask the detection of less abundant menstrual blood specific proteins. For this reason, hemoglobin was removed from collected serum prior to proteome fractionation through use of HemogloBind™ (Biotech Support Group, Monmouth Junction, NJ). This hemoglobin capture reagent is a solid-phase, non-ionic adsorbent product that binds
specifically to hemoglobin allowing for the removal of 80-90% of hemoglobin from serum or red cell lysates. HemogloBind™ does not cross react with most common serum components, making it suitable for the proteomic applications of this research project.”“Here we find another use for HemogloBind™, further validating our unique surface technology approach, not based on biologicals, as being highly selective and an efficient method for the depletion of hemoglobin” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.

The objective of the present study is to identify an oxime antidote, under standardized and comparable conditions, that offers protection against chemical warfare agents or pesticides. Clinical signs of toxicity were observed for 24 h post challenge and blood cholinesterase [AChE and butyrylcholinesterase (BChE)] activity was analyzed utilizing a modified Ellman's method. In the modified Ellman's enzymatic assay for evaluating ChE activity, HemogloBind™, Biotech Support Group's unique solid-phase polymer for hemoglobin depletion, was used for pre-treatment. The article states "Terminal blood samples were collected and processed for all survivors using HemogloBind™".

Biotech Support Group reports on a recent review article which describes the simplicity and efficiency of their proteomic sample preparation technology for selectively depleting hemoglobin, to help solve the dynamic range problem for comprehensive erythrocyte proteome analysis. The citation is: Barasa, Benjamin, and Monique Slijper. "
Challenges for red blood cell biomarker discovery through proteomics." Biochimica et Biophysica Acta (BBA)-Proteins and Proteomics 1844.5 (2014): 1003-1010.In brief, this review describes the many challenges to generate in-depth RBC proteome analysis, such as to obtain pure red blood cells, and to acquire an in-depth proteome, despite the dynamic range problem due to a few highly over-represented RBC proteins – especially hemoglobin which accounts for approximately 97% of the cytosolic mass. The article states "Hemoglobin can also be depleted from an RBC lysate by employing Hemoglobind- [39] or HemoVoid [40] affinity systems. Hemoglobind consist of an elastomeric poly-electrolytic surface that has been optimized to bind Hb from serum samples with high affinity, and can as well be used to remove Hb from RBC lysates [39]. Walpurgis et al. used a complex matrix to deplete the RBC sample for Hb, named HemoVoid, which is made of a library of different ligand combinations, consisting of several kinds of ionic, aromatic, and polymer ligands [40]. Low abundance proteins in the RBC lysate are captured and enriched by the HemoVoid ligand library, while the high abundance proteins such as Hb and CA-I are thought to quickly saturate the system, and they primarily end up in the flow-through. The high abundance proteins in an RBC lysate can thus be easily separated from the low abundance protein fraction. The chosen Hb-depletion approaches by both Alvarez-Llamas et al. [39] and Walpurgis et al. [40] are well compatible with analysis of the RBC protein fractions by 1D or 2D gel electrophoresis, followed by protein identification through mass spectrometry."
"It is worthwhile to note that the authors describe both our strategies for hemoglobin depletion, as the correct choice will vary with the application. With our own experience and with users such as those referenced in this article, we have gained the necessary knowledge to guide our users to the best option for hemoglobin depletion and/or low abundance enrichment" states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.

In this article, measurement of cholinesterase activity prior to depletion and after removing hemoglobin is performed. A comparison of total cholinesterase activity with Ellman method and after Hemoglobind™ treatment prior to Ellman method did not display a statistical difference in mean ChE activity. Ellman's assay invovled measuring the sum of RBC membrane ChE activity and plasma ChE activity. Total cholinesterase activity of whole blood samples with Hemoglobind™ treatment prior to Ellman method is also consistent. Moreover, the Hemoglobind™ protocol is simpler with one incubation and short, low speed centrifugation.This article further validates our unique surface technology approach, not based on antibodies or engineered bio-ligands, as being highly selective and an efficient method for the depletion of hemoglobin concurrent with the recovery of functional activity.

Characterization of Membrane and Cytosolic Proteins of Erythrocytes." In Vascular Proteomics, pp. 71-80. Humana Press, 2013.
Proteomic profiling of erythrocyte proteins to identify novel proteins linked to diseases is an evolving field of clinical proteomics. Cytosolic proteins could contribute to pathology of diseased erythrocytes. Hemoglobin interferes with LC-MS/MS analysis of low abundance cytosolic proteins. Hemoglobin depletion of cytosolic proteins is essential for proteomic sample preparation. Authors Gloria Alvarez-Llamas et al published a chapter in the book Vascular Proteomics titled, Characterization of membrane and cytosolic proteins of erythrocytes, which cites HemogloBind™ from Biotech Support Group for hemoglobin depletion of erythrocyte cells from the cytosolic fraction. A simple method of hemoglobin depletion using HemogloBind™ protocol allows for subsequent downstream proteomic analysis using 2-DE as it reduces major interference of hemoglobin from samples of red blood cells (RBCs) and identifies proteins.

A novel methodology for the analysis of membrane and cytosolic sub-proteomes of erythrocytes by 2-DE. Electrophoresis.2009;30:4095-4108
Authors in this study focused on the analysis of human cytosolic and membrane sub-proteomes. Hemoglobin from samples of red blood cells was studied using different strategies for isolation of the membrane and cytosolic fractions to determine the influence it has on proteome profiling by 2-DE and hemoglobin removal. Biotech Support Group's hemoglobin depletion reagent, HemogloBind™ was successfully used to erythrocyte cells. The results showed that Hemoglobind™ does have a high degree of specificity for hemoglobin and minimal interference. Particularly interesting is how authors developed a novel combined strategy based on hypotonic lysis isolation for identification of high molecular weight proteins (i.e. spectrin, ankyrin) by nano-LC coupled to an LTQ-Orbitrap mass spectrometer.

Site-Specific GlcNAcylation of Human Erythrocyte Proteins: Potential Biomarker(s) for Diabetes Mellitus. Diabetes.2008;58, 309-317.
O-GlcNAc actively cycles on erythrocyte, regulates insulin signaling and is a mediator of glucose toxicity. Therefore studying it may reveal potential biomarker for diagnoses of diabetes. Highly efficient enrichment methods based Hemoglobind™ overcome the challenges of low stoichiometry, suppressed ionization efficiency in presence of unmodified peptides, and intrinsic lability in gas phase mass spectrometric methods. In this paper, authors used Hemoglobind™ to study erythrocyte proteins and compared it with their abundance between normal and diabetic samples proteins. Blood samples were obtained from normal and diabetic patients collected into a vial containing EDTA and OGlcNAcase inhibitor PUGNAc. Next the researchers fractionated the blood cells to isolate erythrocytes. After erythrocytes were lysed and centrifuged, the supernatant containing hemoglobin was partially depleted by HemogloBind™ from Biotech Support Group.

Effect of Hemolysis, High Bilirubin, Lipemia, Paraproteins, and System Factors on Therapeutic Drug Monitoring. Handbook of Drug Monitoring Methods.2008; 97-109.
Bilirubin, hemoglobin, lipids, paraproteins are endogenous interferents of immunoassays used in clinical laboratories which affect therapeutic drug monitoring (TDM), drugs of abuse (DAU) testing, and toxicology assays. Hemoglobin interference is caused by its absorption, fluorescence and chemiluminescence properties. Often assays are repeated with different methods or by removing the interferent from the sample. In this book chapter, authors Datta et al cited HemogloBind™ the synthetic solid phase anionic polyelectrolyte from Biotech Support Group for hemoglobin depletion and reduction of matrix effects.

Clearance of oxidized erythrocytes by macrophages: Involvement of caspases in the generation of clearance signal at band 3 glycoprotein. Biochemical and Biophysical Research Communications.2007; 363(1):57-62
Reduction of erythrocyte clearance by macrophages happens when oxidative stress is decreased either by pretreatment with Hemoglobind™ or enzymes inhibiting caspases causing decreased band 3 aggregation. Band 3 aggregation increased by actions of caspases and was reduced by treatment with caspase inhibitors Z-VAD-fmk or Z-DQMD-fmk (caspase 3 selective) prior to oxidation. Pretreatment of erythrocytes exposed to H2O2 have increased propensity to bind and get phagocyted by macrophages. In this paper authors used anti-band 3 serum to reduce binding and pretreatment of erythrocytes with Hemoglobind™ & polylactosamine-cleaving enzyme.

Relative quantification of glycated Cu-Zn superoxide dismutase in erythrocytes by electrospray ionization mass spectrometry, Biochim Biophys Acta. 1999 Feb2; 1426(3):483-90.
Electrospray ionization mass spectrometry (ESIMS) was used for relative quantification of glycated Cu-Zn superoxide dismutase (SOD-1) in human erythrocytes. SOD-1 samples were prepared from erythrocytes by removing hemoglobin using Hemoglobind™ gel followed by ethanol and chloroform extraction. The reproducibility in measurement of the relative percentage of glycated protein was good, and the standard deviation of each measurement was 4.0%. From the mass spectral analysis of a mixture of commercial SOD-1 and in vitro partially glycated SOD-1 in several ratios, it was found that free and glycated SOD-1 have the same ionization efficiencies.

Peptide
inhibitor of complement C1 modulates acute intravascular hemolysis of
mismatched red blood cells in rats.
TRANSFUSION Volume 00, May 2016.
doi:10.1111/trf.13674. In brief, the
study evaluated the role of a peptide inhibitor of complement C1
(PIC1) in an animal model of acute intravascular hemolysis in both
prevention and rescue scenarios. The authors state "To remove
free Hb that may cause optical interference in bilirubin analysis, we
treated all the samples with Hb depletion from hemolyzed serum/plasma
(HemogloBind). Bilirubin concentration was then measured with a
Bilirubin Assay Kit (Sigma-Aldrich, St. Louis, MO)."

Urine and arterial blood samples were
collected hourly during reperfusion. The article states “Urine
protein levels were measured using an IDEXX Urine Analyzer (IDEXX
Laboratories, Westbook, ME, USA)
following
a 1:3 dilution of urine in HemogloBind (Biotech Support Group,
Monmouth Junction, NJ, USA) to obtain clearer urine samples
after 10 min of vigorous shaking and centrifugation at 12,000× g.”.
