FREMGANGSMAADE TIL FREMSTILLING AF ET IMMOBILISERET ENZYMKONJUGAT OG FORSUKRING AF STIVELSE DERMED

摘要

Disclosed is a process whereby enzymes are immobilized on granular diatomaceous earth. The process involves treating the diatomaceous earth with a polyamine compound having pendant amino groups to cause the polyamine to adhere to the diatomaceous earth leaving pendant amine groups free to react further. The free amine groups are derivatized by treatment with a difunctional compound having amine reactive moieties, so that free amine groups of an enzyme or enzymes can be covalently bound to the polyamine via the amine reactive compound.
