Then enzyme was purified with a deae - cellulose ( 5 . 5x50cm ) column , a toyopearl hw - 65 ( 5 . 5 x 50cm ) column and a sephadex g - 200 ( 5 . 5 x 80cm ) column . finally , the enzyme was purified for 10 folds with the recovery of 17 . 4 % . page showed a single band for the purified creatinase
3 、肌酸水解酶的提纯酶在硫酸铵饱和度为40 80之间完全沉淀，先后经过deae - cellulose离子层析柱、 toyopearlhw - 65疏水层析柱、 sephadexg - 200分子筛层析柱层析，最终使酶提纯10倍，最终得率为17 . 4 。
