This Patent Describes HemoVoid™ To Uncover Proteomic Changes from Autologous Blood-doping


MONMOUTH JUNCTION, NJ, January 15, 2021 — Biotech Support Group reports on a patent application describing the simplicity and efficiency of their hemoglobin depletion technology for human stored red blood cells. The citation is:


Christer, M. A. L. M., et al. “Methods for the detection of autologous blood-doping.” U.S. Patent Application No. 16/976,936.


The patent application relates to the identification of peptides, and the corresponding proteins, that can be used in methods for the detection of autologous blood doping. More specifically, the invention relates to methods comprising tryptic digestion of samples of isolated red blood cell (RBC), specifically isolated RBC cytosol, followed by peptide mapping using liquid chromatography tandem-mass spectroscopy (LC-MS/MS). The invention’s description states “Hemoglobin depletion was performed using HemoVoid resin, buffers and filter tubes as described by the manufacturer (Biotech Support Group) using a standard bench-top centrifuge.”. Upon the preferable depletion of hemoglobin, the methods enable detection of increased levels of certain peptides in samples from subjects that have been subjected to autologous blood doping, compared to samples from non-doped control subjects.


“There is great interest in understanding the proteomic changes in red cells upon storage or in disease states. Being able to quantify these changes using LC-MS/MS is very important to help testing for autologous blood-doping and possibly other conditions. As this patent application describes, proteomic analysis is a very productive way to uncover and measure these important changes. I am pleased that our Hemo-Void™ product is proving to be quite useful for these purposes” states Swapan Roy, Ph.D., President and Founder of Biotech Support Group.
