General description
Thrombin is the final coagulation protease in regard to hemostasis, promoting both procoagulant and anticoagulant effects. Lyophilized powder containing sucrose, sodium chloride and Tris.
Application
Thrombin is used for site specific cleavage of recombinant fusion proteins containing an accessible thrombin recognition site for removal of affinity tags. Thrombin has been used in a study to assess characterization of platelet dysfunction after trauma.
Biochem/physiol Actions
丝氨酸蛋白酶，选择性断开纤维蛋白原中的精氨酸-甘氨酸键，形成纤维蛋白以及纤维蛋白肽 A 和 B。
Physical form
Lyophilized powder containing sodium chloride and Tris-HCl, pH 7.0
Preparation Note
Prepared using bovine lung thromboplastin for conversion to the active form.
Analysis Note
基于 Biggs 改性法的 NIH 分析过程使用 0.2mL 稀释血浆（由血浆与等量生理盐水混合制得）作为底物，以及 0.1mL 凝血酶样品（在含 1% 白蛋白缓冲液中保持稳定）。只使用 15-25 秒之间的凝血时间分析凝血酶浓度。
活性是通过与一种K批次的NIH凝血酶参考标准品进行直接比较而得到并以NIH单位进行表达的。
