Biotech Support Group Release: Hemoglobin Enrichment From Dried Blood Spot (DBS) for Hemoglobin Variant Research  
10/15/2012 1:46:16 PM

PRLog (Press Release) - Oct 14, 2012 -- MONMOUTH JUNCTION, NJ.– HemoVoid™ Blood Card is developed specifically for the purification & enrichment of hemoglobin from blood for hemoglobin variant research. It is compatible with protocols which require direct surface sampling of dried blood spot (DBS) to identify intact proteins. Pharmaceutical testing of DBS samples from clinical matrices for bioanalytical applications during the drug development process favors DBS technology because of reduced animal consumption, reduced shipping costs, storage at ambient temperature and decreased infection risk and toxicity. With HemoVoid™ Blood Card, the enriched hemoglobin voids in flow-through greater than 98% pure, with less than 30 minute bind/wash/elute protocol. Researchers studying hemoglobin variant (HbS, HbE, HbC, HbD, HbF, HbA1c,Thalassemia, etc) should implement HemoVoid™ Blood Card’s efficient protocol. Mild buffer condition maintains tertiary structure and simple transfer to secondary analysis.

The hemoglobin enriched filtrate could have hemoglobin variants, hemoglobin binding proteins or other analytes optimal for biomarker studies. Eluted fractions contains hemoglobin depleted proteins which can be used for developing and validating LC-MS, proteomic studies including protein identification characterizing low abundance proteins for protein biomarker research and gain a broader understanding of the structural, catalytic and signaling functions of such proteins.

HemoVoid™ features an easy to implement sample preparation protocol. It is disposable, cost-effective and high-throughput compatible for the detection of the variant peptides making it an ideal choice for hemoglobin variants discovery for hemoglobin proteomics research. HemoVoid™ , a silica-based protein enrichment matrix, removes hemoglobin from erythrocyte lysate samples while concentrating low abundance, and/or low molecular weight proteins.
