  • Removes hemoglobin from whole blood of diverse species including human, mice, sheep, bovine, goat, rat, etc.

Hemoglobin is a common contaminant from whole blood. The HemoVoid™ Blood Card protocol was designed to substantially reduce the presence of hemoglobin and its associated interference with many serum protein analytes. HemoVoid™ Blood Card is a silica based polyelectrolyte matrix, removes hemoglobin from dried whole blood card samples. The HemoVoid™ protocol uses mild buffers; the protocol conditions are so gentle that native enzyme activity is retained in elution fractions.

Red Blood Cells (RBCs) / Parkinson’s Disease / α-Synuclein

Cao, Chan, et al. " Deep learning-assisted single-molecule detection of protein post-translational modifications with a biological nanopore ." bioRxiv (2023): 2023-09. The authors demonstrate the ability of a biological nanopore, to detect and distinguish α-synuclein-derived peptides bearing single or multiple PTMs, occurring at different positions and in various combinations. To deplete Hemoglobin, the article states “Briefly, RBCs … treated using the HemoVoid kit, … to remove hemoglobin but also to enrich low abundant proteins such as α-synuclein.”


Klatt, Stephan, et al. " Optimizing red blood cell protein extraction for biomarker quantitation with mass spectrometry ." Analytical and Bioanalytical Chemistry (2020): 1-14.

The article describes the advantage of HemoVoid™ in detection of low abundance proteins when comparing their amounts (in percent) between four alternative extraction conditions, stating “… Most peptides, following HemoVoid™ extraction, showed ion abundances ranging between 1.00E+5 and 1.00E+6 (31%). In comparison to this, fewer peptides (10–23%) were within this range following extraction with all other protocols”. With respect to potential biomarkers for Parkinson’s Disease, the article states “For example, PRDX6 accounts for 0.4% of the total ion abundance after DOC (deoxycholate) extraction, whereas following HV ( HemoVoid™) extraction, this increases to 8%, a 20-fold enrichment”. The authors conclude that the HemoVoid™ method significantly reduces the concentration of hemoglobin, resulting in an increased signal-to noise of the remaining red cell proteins.


Elhadi, Suaad Abd, et al.
"αSynuclein in blood cells differentiates Parkinson’s disease from healthy controls ." Annals of Clinical and Translational Neurology. The goal of this study was to determine whether blood cells expressing α-Synuclein can differentiate Parkinson’s disease (PD) from healthy controls. Two proteoforms - PSer129 a-Syn ( phosphorylated pathological form in Lewy bodies) and Oxidized a-Syn levels are observed in blood cells, but both at considerably lower concentration than total a-Syn, so the extremely high abundance of hemoglobin interferes with their analysis. To compensate, the article states for PSer129 α -Syn & Oxidized α -Syn detection by immunoassay, “ followed from hemoglobin clearance with HemoVoid kit”.


Vicente Miranda, Hugo, et al. " Posttranslational modifications of blood-derived alpha-synuclein as biochemical markers for Parkinson’s disease ." Scientific reports 7.1 (2017): 13713.
Posttranslational modifications (PTMs) in aSyn have been identified and implicated on its pathobiology. Since aSyn is abundant in blood erythrocytes, the study aimed to evaluate whether PTMs of aSyn in the blood might hold value as a biomarker for PD. As haemoglobin is the major protein component of erythrocytes lysates (90%), the article states “we depleted this …
using HemoVoid…, enabling the additional concentration of other proteins of lower abundance. We confirmed the aSyn enrichment by immunoblotting (SDS-PAGE and dot-blot).”

For this purpose, the investigation analyzed and compared the protein expression spectrums in the blood of old and young rhesus monkeys. To extract blood cell proteins and deplete Hemoglobin, the article states “Blood cell proteins were lysed with…protein extraction solution (Bestbio, China)…After centrifugation…the supernatants were further depleted of Hemoglobin using HemoVoid™ .” Upon depletion, the study found 1183 proteins expressed differentially in blood cells.

Das, Sonu, et al. " A journey to unravel the pathophysiology of stable and exacerbated Chronic obstructive pulmonary disease through erythrocyte proteomics: A combined mass spectrometry/bioinformatics approach ." (2022). A label free relative quantification of erythrocyte cytosol proteome based on LC-MS/MS was performed on hemoglobin- depleted erythrocyte lysate samples of stable and exacerbated COPD, relative to healthy controls. To deplete Hemoglobin, the article states “ HemoVoid™, … from erythrocyte lysate samples to unmask low abundance…proteins… .”


Pawliński, Łukasz, et al. " Proteomic biomarkers in Gaucher disease ." Journal of clinical pathology 74.1 (2021): 25-29. For proteomics, quantitative analysis was performed by the isobaric tag for a relative and absolute quantitation (iTRAQ) method. The article states “Cells were lysed in lysis buffer (7 mol/L urea, 2 mol/L thiourea, 4% CHAPS, 1% DTT , vortexed, incubated at 25 °C for 30 min and then centrifuged at 12 000 ×g for 15 minthe samples were purified using HemoVoid resin (Biotech Support Group) to remove haemoglobin contamination. The study found 31 proteins that significantly differed in concentration between GDt1 patients and a control group.

The patent application relates to the detection of autologous blood doping. More specifically, the invention relates to methods comprising tryptic digestion of samples of isolated red blood cell (RBC), specifically isolated RBC cytosol, followed by peptide mapping using LC-MS/MS. The invention’s description states “ Hemoglobin depletion was performed using HemoVoid resin … .”. Upon the preferable depletion of hemoglobin, the methods enable detection of increased levels of certain peptides in samples from subjects that have been subjected to autologous blood doping, compared to samples from non-doped control subjects.


Bollenbach, Alexander, et al. " GC-MS and LC-MS/MS pilot studies on the guanidine (NG)-dimethylation in native, asymmetrically and symmetrically NG-dimethylated arginine-vasopressin peptides and proteins in human red blood cells. " Journal of Chromatography B (2020): 122024.

Previous studies showed that human red blood cells are rich in large (> 50 kDa) asymmetric dimethylarginine -containing proteins of unknown identity. The study aimed to report the identity, biological activity and concentration of NG-methylated proteins by using GC-MS and LCMS/MS approaches. The article states “ we included in our method the use of HemoVoid™ to remove specifically most erythrocytic hemoglobin and to improve the SDS-PAGE separation of proteins for further processing. The HemoVoid™, … allowed removal of erythrocytic hemoglobin to a large extent from the hemolysate . … removal of hemoglobin by this technique enabled an effective separation by SDS-PAGE and isolation of bands… .”.


Kitao, Akihito, et al. " Band 3 ectopic expression in colorectal cancer induces an increase in erythrocyte membrane-bound IgG and may cause immune-related anemia ." International Journal of Hematology (2020): 1-10. Autoimmune hemolytic anemia (AIHA) is a rare comorbidity in colorectal cancer (CRC) and has an unknown etiology. To better understand cancer-related anemia, the authors’ investigated ectopic band 3 expression and erythrocyte membrane-bound IgG in a CRC cohort. To reduce the interference from Hemoglobin, the article states “Erythrocytes were lysed … and hemoglobin was depleted using HemoVoid ”.


Rosin-Arbesfeld, Rina, and Ronen SIMAN-TOV. "Article of manufacture and methods for increasing survival of red blood cells." U.S. Patent Application No. 15/739,857. The patent application describes an ex - vivo method of increasing survival of red blood cells (RBCs). The invention’s description states “The Haemolysates were enriched with over 95 % hemoglobin.

Nemkov, Travis, et al. " Hypoxia modulates the purine salvage pathway and decreases red blood cell and supernatant levels of hypoxanthine during refrigerated storage ." haematologica 103.2 (2018): 361-372. The goal of this study was to use proteomics in part to understand hypoxanthine catabolism in vivo for stored red blood cells. It is still unclear whether accumulation of hypoxanthine in stored red blood cell units is clinically relevant for transfused recipients. The article states “ Leukocyte-reduced human RBC from healthy donor volunteers were washed five times in phosphate-buffered saline prior to lysis in distilled water with sonication. Proteomic analyses of RBC membranes and cytosols were performed… RBC cytosolic proteins were depleted of hemoglobin using Hemovoid™ prior to high-pH reversed phase fractionation”.
