| Abstract: | The SOD of bovine erythrocytes have been modified with bovine serum albumin withthe link method of glutarlc dlaldehyde. The retrieval rate of the enzyme activity is 51- 2%,and the modification rate of amino groups is 33.1 %. The m0dified SOD is more stablethan the native upon heating and acldic and baslc enduring and keep good storage stabilityas well. |
