凝血酶 来源于牛血浆

Analysis Note

Activity is expressed in NIH units obtained by direct comparison to a NIH Thrombin Reference Standard, Lot K.

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。

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。
