修饰SOD及未修饰SOD的稳定性比较研究

THE COMPARATION OF THE STABILITY OF MOLECULAR MODIFIED AND UNMODIFIED SUPEROXIDE DISMUTASES

测定了分子修饰ＳＯＤ的酶活力及其在不同温度下的稳定性，与未修饰的ＳＯＤ进行了比较，对在不同温度下测定的结果进行数据处理，经推算得出分子修饰ＳＯＤ在２５℃条件下，保存９５％的酶活力达３．５年，保存９０％的酶活力达７．２年，未修饰ＳＯＤ在２５℃条件下，保存９５％的酶活力为１０３ｄ，保存９０％的酶活力为２１３ｄ。

The activity and the stability of molecular modified superoxide dismutase in differenttemperature were determined, and compared with unmodified superoxide dismutase. The resultsindicate: molecular modified superoxide dismutase`s storage period t0.95 is 3.5 years, t0.9 is 7.2yearsat 25 , unmodified superoxide dismutase's storpe period t0.95 is 103 days, t0.9 is 213 days at 25 .
