Abstract
Immobilized enzymes, intermediates therefor, and a process for the preparation of such substances are described. The method comprises reacting an enzyme with a polymerizable, ethylenically, unsaturated monomer containing a reactive group, and then polymerizing or copolymerizing the covalently-bonded enzyme-monomer product thus produced in the presence of a cross-linking agent and an initiator. The process affords immobilized enzymes of high stability and activity.
