BivalirudinTrifluoroacetate is a specific, reversible and direct thrombin inhibitor with a predictable anticoagulant effect.In patients with normal or mildly impaired renal function, bivalirudin exihibited several notable mechanistic advantages when compared with unfractionated heparin. Bivalirudin showed activity against clot-bound thrombin, inhibition of thrombin-induced platelet activation, short plasma half-life (25 minutes)[1]. Bivalirudin inhibited both circulating thrombin and fibrin bound thrombin directly by binding to thrombin catalytic site and anion-binding exosite I in a concentration-dependent manner. Bivalirudin prolonged activated partial thromboplastin time, prothrombin time, thrombin time and activated clotting time (ACT). ACT levels activated by bivalirudin showed no correlation with its clinical efficacy [1]. When compared to heparin alone or heparin in combination with-a GpIIb/IIIa inhibitor, bivalirudin had shown less in-hospital major bleeding. Bivalirudin was safe and effective during percutaneous coronary intervention (PCI) in patients with heparin-induced thrombocytopenia, indicated the safety and efficacy of bivalirudin [1].Reference:[1].

注意事项:
抗逆滴加序列
每次向板内滴加抗原时,移液器滴头要与平面45度悬空,不要触碰到孔内的液体,由后向前依次滴加(即浓度由低往高滴加)。
抗感染反应期
抗原抗体在室温20~25℃下,必须反应30min以上,若环境温度低于室温,可将微量反应板置于恒温培养箱中,使二者充分反应。
旅游温度
磷酸盐缓冲液的pH值要在高压灭菌后进行滴定,往往在高压后pH值会有所改变,所以高压后再调一次pH值更为准确。磷酸盐缓冲液一经使用保存期不要超过3周。当pH<5.8时,红细胞会产生自凝现象;当pH>7.8时,图形洗脱加快,易造成肉眼观察产生误差;p H=7.2时,红细胞沉降最充分,图形最清晰。
当滴注 1%红细胞悬液时,应经常摇晃红细胞悬液,使红细胞均匀地分布在磷酸缓冲液中,以防止红细胞下降。
反应时间及温度
加入鸡红血球之后,反应板在室温(20~25℃)静置30~40min,对照孔血球下沉于孔底,即可判定结果。若室温达不到实验要求,需相应调整反应时间。当环境温度低于4℃时,红细胞发生自凝;高于37℃时,会发生反应物分离和红细胞溶血。
使用方法:
1.本蛋白酶抑制剂混合物为100×的储存液,使用时按照1:100的比例加入到裂解液中(例如,1ml裂解液中加入10μl蛋白酶抑制剂混合物),混匀后即可使用。根据需要,0.5M的EDTA也按照1:100的比例加入到裂解液中(如用于检测金属蛋白酶活性,则不宜添加EDTA)。含有蛋白酶抑制剂混合物的裂解液宜现用现配,不宜配制后冻存待后续使用。
2. 待所需的抑制剂添加完毕混匀后,就可以开始进行哺乳动物组织的裂解和蛋白提取。

:(略) 基于保护基团的类别,必须使用去保护剂的组合。 例如, 当Boc和tButyl存在时,它们的Carbocation对应物能与Trp, Tyr和Met反应形成tbutyl产物。EDT是极有效的t-butyl trifluoroacetate清除剂, 但它不保护Trp。 因此,必须加水以控制烷基化。Trp的吲哚环和Tyr的OH极易与Pmc反应。水再次表现出对此反应的抑制。Trt和Mtr基团也有相似情形。较此适当组合清除剂将极大降低副反应。 tBoc和CBZ多肽合成
