摘要
利用高软弱阴离子交换色谱法简化了超氧化物歧化酶(SOD)的纯化手续。在丙酮沉淀后,仅用一步色谱分离就能使来自牛血的Cu,Zn-SOD达到电泳纯,活性回收率为86.4%,比活为7711U/mg,纯化倍数提高至52倍。此外,详尽讨论了色谱分离的条件。
e procedure of purifying superoxide dismutase was simplified using high performance weak anion ex-change chromatography.In only one chromatographic step following the acetone precipitation,Cu,Zn-super-oxide dismutase from bovine erythrocytes was purified to electrophoretic homogeneity wit h a recovery of86.4%. The specific activity of the enzyme preparation was 7711U/mg,and its purity was increased upto to52-fold.The conditions of chromatographic separation were also discussed in detail.
