摘要
用硫酸铵作为盐析剂沉淀尿激酶溶液中蛋白质,符合Cohn经验式:logS=β-Ksm。结果表明:常数β值随pH和温度而变化,盐析常数Ks与温度或pH基本无关。
Total protein precipitation in the urokinase with ammonium sulphate as salting-out agent fits empirical eqtiation of cohn:lgs=β-Ks m. The result shows that constant changes with pH and the temperature. Salting-out of constant Ks almost doesn't contact with the temperature or pH.
