MONMOUTH JUNCTION, NJ, September 14, 2017 -- Biotech Support Group reports on a recent research article describing the simplicity and efficiency of their hemoglobin depletion technology for analyzing enzyme activities from enriched red cell soluble sub-proteomes. The citation is:

Cortese-Krott, Miriam M., et al. "Identification of a soluble guanylate cyclase in RBCs: preserved activity in patients with coronary artery disease." Redox Biology (2017).

In brief, the authors aimed to investigate whether RBCs carry a functional soluble guanylate cyclase (sGC) signalling pathway and to address whether this pathway is compromised in coronary artery disease. The article states “Using a commercial resin (HemoVoid™), which removes hemoglobin… and allows enrichment of soluble cytoplasmic proteins, we established a procedure that allows fast and reliable preparation of hemoglobin-free cell lysates from as little as 1-2 ml blood. In those samples, expression and activity of the cGMP-generating sGC, cGMP-hydrolyzing PDE5 and cGMP-transducing PKG was assessed by enzymatic assays and Western blot analysis”. The authors conclude that human and murine RBCs carry a catalytically active a1ß1-sGC (isoform 1), which converts 32P-GTP into 32P-cGMP, as well as PDE5 and PKG. Collectively, the article demonstrates that an intact sGC/PDE5/PKG-dependent signaling pathway exists in RBCs, which remains fully responsive to NO and sGC stimulators/activators in patients with endothelial dysfunction.


“One of the key advantages for all our products is the maintenance of functional activity post-separations. This article illustrates the importance of not only removing the influence of hemoglobin in order to perform proteomic analysis of red cells, but that the activities of the soluble RBC enzymes are preserved and can be monitored for differential function in disease” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
