Bovine ligamentum nuchae elastin that had been partially digested by porcine pancreatic elastase and then thoroughly washed with 0.2 M-NaC1/0.05 M-sodium borate solution continued to release peptide fragments in solution. Complete removal of elastase from the elastin surface required extraction with dilute alkali, a procedure that does not irreversibly inactivate the enzyme or hydrolyse elastin.
经猪胰弹性蛋白酶部分消化后,再用0.2M氯化钠/0.05M硼酸钠溶液充分洗涤的牛项韧带弹性蛋白,在溶液中持续释放肽片段。从弹性蛋白表面完全去除弹性蛋白酶需要用稀碱提取,该过程不会使酶不可逆地失活或水解弹性蛋白。
