Аннотация:Chromatographic material based on tryptophilthreonyltyrosine and efficiently binding human,
sheep, goat, and bovine immunoglobulin G was obtained. High selectivity of the sorbent for extraction of immunoglobulins from blood plasma has been demonstrated. Effective sorption capacity is 15–25 mg of immunoglobulin G per 1 ml of the matrix. Optimization of the method of triptophylthreonyltyrosine covalent binding to the polysaccharide matrix allowed the achievement of high sorbent stability in conditions of use and storage. This sorbent may be used in medicine and biotechnology. Keywords: affinity sorbent, tripeptide, tryptophylthreonyltyrosine as a ligand, immunoglobulins, affinity chromatography.
