Methods for quantitative analysis of immobilized trypsin 备用胰蛋白酶的定量分析法
2.
The hydrochloric acid in gastric juice is the main cause of the inactivation of pigg 相对而言，胃酸造成的变性要较胰蛋白酶的水解对pigg活性的影响更大。

2 ) hanks " buffer of trypsin not being added edta could obtain better the growth potential and the subsequent attachment of harvested skin cells t then it being added edta have better digested potent 与添加edta相比，用只含胰蛋白酶的hanks '液处理贴壁细胞，所回收的传代细胞存活能力较好；而添加edta的胰蛋白酶消化液消化能力较强。

3 ) dispased cold digested single cell is the best to obtain pured epithelial cell line ; it is appropriate to obtain pured fibroblast cell line that repeated attachment and the pured method to their different sensibility to trypsin 对于秦川牛皮肤上皮细胞与成纤维细胞的纯化： dispase冷消化单细胞培养的效果最佳，可获得纯化的上皮细胞系，而根据二者对胰蛋白酶的敏感性不同的分离方法、反复贴壁法适宜于获得纯化的成纤维细胞系。
