The average yield and enzyme activity extracted by SP resin were compared with those by 113 resin, J_2 resin and Amberlite CG50. The experiment showed that kallikrein in the mother solution in which elastase had been removed by SP resin could be prepared.

• 同时还将SP树脂与国内生产弹性酶的J_2树脂、113树脂及Amberlite CG50进行了比较。 实验结果表明:利用SP树脂吸附弹性酶后的母液仍可回收胰激肽释放酶。
