PRLog (Press Release) - Mar. 26, 2013 - MONMOUTH JUNCTION, N.J. -- Monmouth Junction, NJ: Biotech Support Group LLC, reports on a new technical poster which describes the use of on-bead digestion protocols as a suitable method to generate peptides for LC-MS/MS analysis, after albumin depletion on its AlbuVoid™ product. Entitled “New On-Bead Digestion Protocols Improve LC-MS Workflows Of Albumin Depleted Samples”, it was presented at the US HUPO Conference in Baltimore, MD, March 10-11, 2013. It describes by several performance metrics, that the ‘on-bead’ digestion protocol is comparable to the product’s standard elution protocol. On-bead protocols provide advantaged speed, simplicity and reduced potential for keratin contamination. The poster also reports on the efficiency of AlbuVoid™ as a simple consumable product for albumin depletion, with 20-30% more protein/peptide identifications achievable relative to untreated plasma, under identical operating and informatic parameters.

“With greater interest in the proteomics community for better workflows and performance for LC-MS analyses, direct proteolytic digestion of the bound protein content - commonly called on-bead digestion, has many desirable workflow advantages. With this report on AlbuVoid™, we have now demonstrated that the surface chemistry platform from which it was derived, our novel passivated porous silica – NuGel™, offers the rigidity and low water content ideal for protein concentration and proteolytic digestion”, states Swapan Roy, Ph.D, President & Founder of Biotech Support Group. “We envision designing new strategies for high abundance depletion that can utilize on-bead digestion workflows for highly complex bead-bound proteomes along with many chemical proteomic applications.”
