METHOD OF IMMUNOSORBENT PREPARING Russian patent published in 2002 - IPC

FIELD: microbiology. SUBSTANCE: vermiculite or mixture of vermiculite with magnetic powder taken in the ratio = 1.5:2 is used as a base. Modification is carried out by base incubation with saturated solution of colloidal sulfur in benzene at temperature 20-25 C for 60 min, drying under ventilation without heating, suspending in 3% dextran T-20 solution at temperature 20-25 C for 60 min. A carrier is dried at 100-110 C for 30 min and after its grinding sifting is carried out through a sieve with cell size 130 mcm followed by covalent binding protein ligand with a carrier. The proposed method ensures to obtain immunosorbent with low nonspecific adsorption and enhanced immunochemical activity. EFFECT: improved method of preparing, valuable properties of sorbent. 1 tbl
