應用

针对内皮细胞培养物传代进行了优化。
来源于大豆的胰蛋白酶抑制剂用于以下应用:
  • 分散的腺泡的过滤和接种
  • 磷酸化 tau 和免疫印迹分析的相对定量
  • VIL-4 和 IL-4 cDNA 的亚克隆化和转化,以及蛋白质表达和纯化(来源于大豆的胰蛋白酶抑制剂作为阳性对照)。

生化/生理作用

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。

其他說明

含有色谱纯化的大豆胰蛋白酶抑制剂和补铁小牛血清。

單位定義

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。

準備報告

在 Dulbecco′s 磷酸盐缓冲盐水中制备,不含钙和镁。
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。
