應用
用于消化胶原蛋白并从基质中释放贴壁细胞。
该产品适用于人类肿瘤、小鼠肾脏、人类成人和胎儿脑、肺和许多其他上皮组织的解聚。研究表明,它适用于肝脏和肾脏的灌注研究、胰腺消化、非实质大鼠肝细胞分离和肝细胞制备。胶原酶也用在糖基化终末产物的研究中制备动脉组织。经测试,该酶以约 1mg/mL 的浓度消化肝细胞。消化浓度范围为 0.1 至 5 mg/mL。
生化/生理作用
每摩尔胶原蛋白酶被4g原子钙活化。 它被乙二醇-双(β-氨基乙基醚)-N,NN′,N′-四乙酸,β-巯基乙醇、谷胱甘肽、巯基乙酸和8-羟基喹啉抑制。
胶原酶产物是 C. histolyticum分泌的酶混合物,可通过分泌酶中10-18个组分的相对比率来区分不同的产物。 其主要成分是两种胶原酶、梭菌蛋白酶、和一种中性蛋白酶。 这些酶的协同作用可降解胶原蛋白和其他细胞内物质。胶原酶和中性蛋白酶的作用对于从组织中有效释放细胞均是必需的。 各种类型的胶原蛋白都是胶原酶的天然底物。
注意
未开封的产品可在-20°C下稳定保存一年。在37℃、50℃和-20℃下储存30天,FALGPA或蛋白酶活性无损失。如果将粗制胶原酶溶液分装(10 mg/mL)后快速冷冻并冷藏在-20℃下,可稳定保存。后续的冻融循环将破坏溶液。若将本品放在冰上,可在7小时内保持100%活性。
單位定義
一个胶原蛋白消化单元(CDU)从牛跟腱胶原蛋白中释放的肽链量和1.0 μ亮氨酸,5小时,pH7.4,37℃,在钙离子存在下的茚三酮颜色相同。一个 FALGPA水解单元每分钟,25℃,水解1.0 μmole 呋喃基丙烯酰-Leu-Gly-Pro-Ala。一个中性蛋白酶单元水解酪蛋白,产生颜色和1.0 μmole 酪氨酸每5小时,pH7.5,37℃下产生的相同。一个梭菌蛋白酶单元在DTT存在下,pH7.6,25℃,每分钟水解1.0 μmole BAEE。
準備報告
这种胶原酶是从 VII 型(C0773)溶组织性梭菌培养滤液中获得的。人们认为该培养滤液含有至少 7 种分子量为 68-130kDa 的不同蛋白酶。通常使用 TESCA 缓冲液(含有 50 mM TES,0.36 mM 氯化钙,pH 7.4,37℃)以 1-2 mg/mL 制备溶液。
