Biotech Support Group reports on a recent research article which describes the simplicity and efficiency of their proteomic sample preparation technology for albumin depletion. Urine exosome isolation via ultracentrifugation, followed by albumin depletion provides researchers with knowledge of renal regulation and could lead to the identification of biomarkers for diabetic nephropathy and diabetic mellitus. By removing albumin using AlbuSorbTM, the authors identified more urinary proteins such as flotillin-2, lamp-1, PODXL, tsg-101 from exosome fractions of urine samples.
