Abstract
- Copper, zinc superoxide dismutase (Cu,Zn SOD) has been purified to homogeneity from chicken erythrocytes by anion-exchange, immobilized metal affinity and size exclusion chromatography. 2. Molecular properties (amino acid composition, molecular mass, subunit composition and spec. act.) of the chicken enzyme are similar to those of a bovine erythrocyte Cu,Zn SOD. 3. The chicken and bovine enzymes are immunologically similar since antisera raised against each enzyme are cross-reactive.
摘要
- 利用阴离子交换、固定化金属亲和及尺寸排阻色谱法，已从鸡红细胞中纯化出均一的铜锌超氧化物歧化酶（Cu,Zn SOD）。2. 鸡源酶的分子特性（氨基酸组成、分子量、亚基组成及比活性）与牛红细胞Cu,Zn SOD的相似。3. 鸡源和牛源酶在免疫方面相似，因为针对每种酶产生的抗血清具有交叉反应性。
