Abstrakt: Trypsin modified by dextran preactivated with 2-amino-4,6-dichloro-1,3,5-triazine or ethyl chloroformate has been prepared. Properties of the resulting conjugates with respect to hydrolysis of synthetic substrates--methyl ester benzoyl L-arginine and n-nitrophenyl ester of n'-guanidine benzoic acid as well as high molecular weight substrates--casein and fibrin--have been studied. Stability of conjugates during autolysis and irreversible heat denaturation has been investigated.
