一般說明
冻干粉末，含有蔗糖、氯化钠和Tris。
凝血酶是止血过程中的最终凝血蛋白酶，可同时促进促凝血和抗凝血作用。
應用
凝血酶被用于重组融合蛋白的位点特异性切割，这些重组融合蛋白具有可接近的凝血酶识别位点以除去亲和标签。凝血酶已应用于一项研究，以评估用于小尺寸血小板微粒的流式细胞术的创新方法。
生化／生理作用
选择性裂解纤维蛋白原中 Arg-Gly 键形成纤维蛋白和纤维蛋白肽 A 和 B 的丝氨酸蛋白酶。
單位定義
活性以NIH单位表示，它是通过与NIH凝血酶参考标准品直接对比而获得的
分析報告
NIH测定程序根据Biggs改进方法，使用0.2ml稀释血浆（与生理盐水1:1）作为底物以及0.1ml凝血酶样本（在1%缓冲白蛋白溶液中稳定）。仅在15-25 秒的凝血时间内测定凝血酶浓度。
