一般描述

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。
凝血酶由肝脏中的非活性凝血酶原蛋白水解产生。它是具有四个结构域的糖蛋白:包含Gal域的10 γ羧化谷氨酸,两个kringle域和胰蛋白酶样丝氨酸蛋白酶结构域。凝血酶原基因位于人类染色体11p11.2上。

应用

人血浆凝血酶已用于:
  • 的制备纤维蛋白凝胶,以评估人骨髓基质细胞(hBMSC)形态
  • 血小板活化
  • 评估内皮细胞(EC)单层完整性

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。

生化/生理作用

凝血酶的主要功能是将纤维蛋白原裂解为纤维蛋白,帮助稳定凝块形成。凝血酶原基因的广泛突变造成自身缺陷,导致凝血异常,如凝血酶原异常和凝血酶原低下。高水平的凝血酶可在多巴胺能神经元中引起神经毒性,并导致帕金森病恶化。通过调整凝血酶水平,可调节多发性硬化症的凝血途径。冠心病(CAD)患者的凝血酶水平会升高。凝血酶在大脑神经原纤维缠结中积累可能有助于tau蛋白聚集,形成阿尔茨海默氏病病理。
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。凝血酶在一项研究中被用于研究蛋白C通路在肠屏障功能中的作用。
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。

单位定义

直接与NIH凝血酶参考标准比较而得到NIH单位表示的活性

外形

由生理盐水柠檬酸钠缓冲液,pH 6.5,制得冻干粉

分析说明

NIH 试验步骤基于 Biggs 方法的改进,使用 0.2mL 稀释血浆(与生理盐水 1:1 混合,作为底物)和 0.1mL Biggs 凝血酶样品(稳定于 1% 缓冲白蛋白溶液中)。只使用 15-25 秒之间的凝血时间分析凝血酶浓度。

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. Can a stock solution of Product T6884, Thrombin, be stored frozen?

    A suggested stock solution is 100 units/ml. The solution should contain 0.1% BSA for stability and may be stable for about one week at 0-5°C. Since thrombin solutions adsorb to glass, it is recommended to aliquot the solutions in plastic tubes and store at -20°C or below.
