【摘要】 研究了牦牛血红细胞Cu、Zn-SOD的部分理化性质,结果表明其分子量、紫外吸收率与黄牛SOD的接近,而在Cu和Zn的含量方面存在较大差异。牦牛Cu、Zn-SOD对pH及温度的变化不敏感,但抗胰蛋白酶和抗H₂O₂的能力稍差。更多还原

【Abstract】 The partial physicochemical properties of Cu, Zn-SOD from yak red blood cells were studied, which results revealed the molecular weight and ultraviolet absorpsion spectrum of yak Cu, Zn SOD was similar to that of yellow cattle ones but in copper or zinc level there was larger difference. Yak Cu, Zn-SOD was insensitive to changes of pH and temperature but more sensitive to trypsin and hydrogen dioxide solution.更多还原
