Biochem/physiol Actions
该抑制剂能够在较小程度上抑制胰蛋白酶、胰凝乳蛋白酶和纤溶酶。它还能抑制蛋白酶血浆激肽释放酶和凝血因子X，机制与抑制胰蛋白酶类似。胰蛋白酶抑制剂不会抑制金属蛋白酶、基于组织的激肽释放酶、酸性蛋白酶或硫代蛋白酶。该抑制剂通过与蛋白酶活性位点按1:1化学计量形成复合物，然后在抑制剂上切割单个精氨酸-异亮氨酸键。抑制作用是可逆的且具有pH依赖性。
Preparation Note
胰蛋白酶抑制剂能够以10 mg/mL溶于水和磷酸盐缓冲液。它能够以1 mg/mL溶于平衡盐溶液和无血清培养基中。浓度大于10 mg/mL的浓缩液可能浑浊，呈黄色至琥珀色。使用胰蛋白酶消化细胞后，重悬于胰蛋白酶抑制剂溶液中，使得用于解离的胰蛋白酶溶液浓度达到1 mg/mL。然后将细胞悬浮液以1000rpm离心，得到细胞沉淀。
在2-8℃下短期储存时，溶液可保持活性。溶液分装后可在-20℃冷冻并保持稳定。

Analysis Note
1 mg 胰蛋白酶抑制剂，将抑制最低 1.0 mg 胰蛋白酶活性，约 10,000 BAEE 单位/mg 胰蛋白酶。
Other Notes
一个胰蛋白酶单位是指在25°C、pH 7.6条件下，以N-α-苯甲酰基-L-精氨酸乙酯（BAEE）为底物，每分钟产生0.001的 A253所需的酶量。
一个胰蛋白酶单位每分钟将产生 0.001 的 ΔA253，BAEE 作为底物，pH 值为 7.6，温度为 25℃；反应体积 3.2 ml，光程为 1 cm。
大豆胰蛋白酶抑制剂是在由两个二硫键交联的单个多肽链中含有 181 个氨基酸残基的单体蛋白质。
