By this method, we can obtain high specific activity,high stability and high recovery rate modified SOD. The modified SOD exhibits more stability towards temperature,pH and human gastric juice as compared with natural SOD,and it can be stored in room temperature for a long time. This product can enlarge the applicable facet of SOD.Then it has abroad social and economic benefits. 超氧化物歧化酶 化学修饰 月桂酸 稳定性 superoxide dismutase chemical modification lauric acid stability Q550.3 1998-04-01 2021-04-01 4
