MONMOUTH JUNCTION, N.J. - eTradeWire -- Biotech Support Group reports on a research article describing the simplicity and efficiency of their hemoglobin depletion technology for enriching erythrocyte proteins, in order to assess proteomic differences associated with COPD by LC-MS analysis.

The citation is:

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 (https://assets.researchsquare.com/files/rs-2295...)." (2022).

Chronic Obstructive Pulmonary Disease (COPD) is a progressive lung disorder with high mortality. The present study, explores the novel and highly enriched protein networks differentially expressed in stable and exacerbated COPD variants to elucidate the disease pathophysiology. 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™, a silica-based protein enrichment matrix from Biotech Support Group USA, was used to remove hemoglobin from erythrocyte lysate samples to unmask low abundance…proteins according to the manufacturer's protocol." The article describes five highly enriched protein clusters in stable and seven in exacerbated COPD, and specific proteins unique to exacerbated COPD, that could help in differentiating stable and exacerbated COPD clinically.

"It's very rewarding to see that for Hemoglobin removal, HemoVoid™ was an essential product to enrich the red blood cell proteome for this study. Without such an efficient enrichment of the low abundance proteome, the pathways and potential biomarkers associated with exacerbated COPD would not have been observed in the LC-MS proteomic analysis.", states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
