Summary for Patent: 4,415,663
Title: Support matrix for immobilized enzymes
Abstract:A support matrix comprising a porous support impregnated with a polyamine substantially all of whose nitrogens bear pendant epoxide groups can be readily used to immobilize enzymes. Because immobilization results from formation of a hydrolytically stable carbon-nitrogen single bond, the resulting immobilized enzyme system may be advantageously used where hydrolytic instability of the bound enzyme is an important consideration.
