PRLog (Press Release) - May 1, 2013 -- MONMOUTH JUNCTION, NJ.– Proteomic profiling of erythrocyte proteins to identify novel proteins linked to diseases is an evolving field of clinical proteomics. Cytosolic proteins could contribute to pathology of diseased erythrocytes. Hemoglobin interferes with LC-MS/MS analysis of low abundance cytosolic proteins. Hemoglobin depletion of cytosolic proteins is essential for proteomic sample preparation. Authors Gloria Alvarez-Llamas et al published a chapter in the book Vascular Proteomics titled, Characterization of membrane and cytosolic proteins of erythrocytes, which cites HemogloBind™ from Biotech Support Group for hemoglobin depletion of erythrocyte cells from the cytosolic fraction. A simple method of hemoglobin depletion using HemogloBind™ protocol allows for subsequent downstream proteomic analysis using 2-DE as it reduces major interference of hemoglobin from samples of red blood cells (RBCs) and identifies proteins.
