Popis: Chromatographic material based on tryptophil-threonyl-tyrosine 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 triptophyl-threonyl-tyrosine 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.
