Cao,Chan, et al. " Deeplearning-assisted single-molecule detection of proteinpost-translational modifications with a biologicalnanopore ." bioRxiv (2023):2023-09. The authors demonstrate the ability of a biologicalnanopore, to detect and distinguish α-synuclein-derived peptidesbearing single or multiple PTMs, occurring at different positions andin various combinations. To deplete Hemoglobin, the article states“Briefly, RBCs… treated using the HemoVoid kit, … to remove hemoglobin but also to enrich low abundantproteins such as α-synuclein.”
Klatt,Stephan, et al. " Optimizingred blood cell protein extraction for biomarker quantitation withmass spectrometry ." Analyticaland Bioanalytical Chemistry (2020):1-14.
Thearticle 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, showedion abundances ranging between 1.00E+5 and 1.00E+6 (31%). Incomparison to this, fewer peptides (10–23%) were within this rangefollowing extraction with all other protocols”. With respect topotential biomarkers for Parkinson’s Disease, the article states“For example, PRDX6 accounts for 0.4% of the total ion abundanceafter DOC (deoxycholate) extraction, whereas following HV ( HemoVoid™)extraction, this increases to 8%, a 20-fold enrichment”. Theauthors conclude that the HemoVoid™ method significantly reducesthe concentration of hemoglobin, resulting in an increased signal-tonoise of the remaining red cell proteins.
Elhadi,Suaad Abd, et al. "α‐Synucleinin blood cells differentiates Parkinson’s disease from healthycontrols ." Annalsof Clinical and Translational Neurology. Thegoal of this study was todetermine whether blood cells expressing α-Synuclein candifferentiate Parkinson’s disease (PD) from healthy controls. Two proteoforms- PSer129 a-Syn( phosphorylatedpathological form in Lewy bodies) andOxidized a-Synlevels are observed in blood cells, but both at considerably lowerconcentration than total a-Syn,so the extremely high abundance of hemoglobin interferes with theiranalysis. To compensate, the article states for PSer129 α -Syn &Oxidized α -Syn detection by immunoassay, “ followedfrom hemoglobin clearance with HemoVoid kit”.
VicenteMiranda, Hugo, et al. " Posttranslationalmodifications of blood-derived alpha-synuclein as biochemical markersfor Parkinson’s disease ." Scientificreports 7.1(2017): 13713.
Posttranslational modifications (PTMs) in aSyn have beenidentified and implicated on its pathobiology. Since aSyn is abundantin blood erythrocytes, the study aimed to evaluate whether PTMs ofaSyn in the blood might hold value as a biomarker for PD. Ashaemoglobin is the major protein component of erythrocytes lysates(90%), the article states “we depleted this … using HemoVoid…, enabling the additional concentration of otherproteins of lower abundance. We confirmed the aSyn enrichment by immunoblotting (SDS-PAGE and dot-blot).”
