【摘要】 应用戊二醛交联法研究了牛血清白蛋白对牛红细胞SOD的化学修饰，修饰酶活力回收率为51．2％，氨基修饰率为33．1％．SOD经牛血清白蛋白修饰后提高了耐热、耐酸碱稳定性，并保持良好贮藏稳定性．更多还原

【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.更多还原
