COPOLYMERS OF ACRYLAMIDE GAS

摘要

Water insoluble biologically active proteins are bound on novel copolymers consisting of (a) acrylamide (b) ethylene-maleic acid or its anhydride and/or (c) maleic acid and/or its anhydride and (d) N,N'-methylene-bis-acrylamide or ethylene diacrylate in a weight ratio a:b:c:d of 3 : 0.5 - 1.5 : 0.05 - 4 : 0.075 - 0.9, the weight ratio a : (b + c) being not more than 4, to provide compositions which are outstanding in their ability to yield up the bound protein, and with which precise substrate reactions can be carried out.
