METHOD FOR OBTAINING COLLOIDAL GOLD CONJUGATES WITH IMMUNOGLOBULINS IN THE MANUFACTURE OF IMMUNOCHROMATOGRAPHIC TEST SYSTEMS

摘要

FIELD: biotechnology. ;SUBSTANCE: invention relates to biotechnology. The method for obtaining colloidal gold conjugates with immunoglobulins provides for the separation of the conjugate from unbound immunoglobulins and a free secondary stabilizer by layering the reaction mixture on a drying medium consisting of 0.025 M of tris buffer, 0.1 M of NaCl, sucrose and bovine albumin, followed by centrifugation. ;EFFECT: invention makes it possible to reduce the time for obtaining conjugates. ;1 cl, 1 ex
