The immobilization of the enzymeE. coli L-asparaginase on polysaccharides. III. Covalent binding with 3-bromo-2-hydroxypropyldextran

The synthesis of immobilized L-asparaginase on 3-bromo-2-hydroxypropyldextran has been effected. Some physicochemical properties of the preparations obtained have been studied. A stabilizing effect of the modification on the heat stability of the L-asparaginase has been detected. The influence of the bound polymer on the antigenic properties of the enzyme have been established.Institute of Organic Synthesis, Academy of Sciences of the Latvian SSR, Riga.
