一般說明
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
凝血酶用于位点融合蛋白的位点特异性裂解，重组融合蛋白含有可进入的凝血酶识别位点，用于去除亲和标签。在一项研究中，凝血酶被用于评估用于生物物理学和结构表征的腺苷受体肽生物合成的表达和纯化系统。
生化／生理作用
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。
單位定義
活性以NIH单位表示，通过与NIH凝血酶参考标准品直接对比来测定。
重構
当使用 1mL 水复原时，小瓶将在 0.15M 氯化钠和 0.05M 柠檬酸钠中以及 pH 6.5 下达到规定的活性。
分析報告
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。

Platelet-rich plasma (PRP) is typically isolated and applied immediately after preparation, making it both a time- and labor-intensive addition to the operative procedure. Thus, it would be convenient if PRP could be preserved. We evaluated the efficacy of freeze-dried PRP

Polymer nanoparticles (NPs), due to their small size and surface functionalization potential have demonstrated effective drug transport across the blood-brain-barrier (BBB). Currently, the lack of in vitro BBB models that closely recapitulate complex human brain microenvironments contributes to high failure
