Abstract
An improved method of preparing support matrices, characterized as inorganic oxides impregnated with a polyamine cross-linked with a bifunctional reagent so as to furnish a plurality of pendant functional groups, comprises impregnating the oxide at a pH less than about 4 and subsequently curing the polyamine-impregnated oxide at a pH from about 8 to about 12. This improved method leads to subsequently prepared immobilized enzyme systems whose activity is increased by about 35%.
