产品简介抑肽酶(Aprotinin),又称为抑蛋白酶肽,是一种竞争性、可逆的丝氨酸蛋白酶抑制剂,可与丝氨酸蛋白酶形成稳定复合物并阻断酶的活性位点,这种结合是可逆的,大多数的抑肽酶-蛋白酶复合物在极端的pH<3.0的条件下解除结合。抑肽酶抑制糜蛋白酶、胰蛋白酶、激肽释放酶和血纤维蛋白溶酶,不能抑制Xa因子和凝血酶。从结构上来说,抑肽酶是一种来自牛肺的单体球状蛋白,由58个氨基酸组成并排列在具有三个交联二硫键的单个多肽链中。重组抑肽酶采用大肠杆菌表达,在GMP法规下生产,不含任何动物源成分,无动物源性的病毒污染,氨基酸序列与来源于牛肺的抑肽酶完全一致,具有与动物源性抑肽酶相同的酶学性质,可替代动物源性抑肽酶用于各种生物技术过程中,如:重组蛋白生产中抑制丝氨酸蛋白酶的活性;细胞培养等。另外,也提供来源于牛肺的抑肽酶(动物源性)酶活单位:能抑制1个胰蛋白酶单位的活力称为1个抑肽酶活力单位(EPU)。储存条件冻干粉2~8℃保存,有效期2年。使用方法抑肽酶与蛋白酶是等摩尔有效结合,推荐的结合pH>6.0,在pH<3.0的条件下不结合。可直接使用0.9%NaCl溶解,溶解后可-20℃储存。
