應用
抑肽酶被大量用作胰蛋白酶抑制剂。
生化／生理作用
抑肽酶是一种竞争性丝氨酸蛋白酶抑制剂，可与酶的活性位点组成稳定的复合酶并同时对其进行封闭。 这种结合是可逆的，而且绝大多数抑肽酶-蛋白酶复合物可在极端的pH >10 or < 3水平时发生解离。 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。
單位定義
一个胰蛋白酶抑制剂单位（TIU）可将两个胰蛋白酶单位的活性降低50％，而其中一个胰蛋白酶单位在pH 7.8和25℃下可每分钟水解1.0 μ摩尔的N-α-苯甲酰基-DL-精氨酸对硝基苯胺。另一种常用的单位是KIU，而1 TIU = 1,300 KIU。
準備報告

Skilful surgery combined with blood-saving methods and careful management of blood coagulation will all help reduce unnecessary blood loss and transfusion requirements. Excessive surgical bleeding causes hypovolaemia, haemodynamic instability, anaemia and reduced oxygen delivery to tissues, with a subsequent increase

While aprotinin and bovine pancreatic trypsin inhibitor (BPTI) are the same protein sequence, the term aprotinin is typically used when describing the protein derived from bovine lung.
实验方案
Objective: To standardize a procedure for the enzymatic assay of Aprotinin.
