Betrixaban is a highly potent, selective, and orally efficacious inhibitor of factor Xa with IC50 value of 1.5nM [1].
Betrixaban shows excellent anticoagulant potency in vitro. In the rabbit deep vein thrombosis model, the concentration of betrixaban required to double the rabbit prothrombin time is below 2μM. Betrixaban is selective for fXa and has poor activity for thrombin, trypsin, t-PA and aPC. The patch clamp hERG assay shows that betrixaban has low affinity with hERG suggesting it is safer than other candidate compounds. In addition, betrixaban displays a profile of good oral bioavailability and oral exposure, long half-life in animal models. It has bioavailability of 51.6% at dose of 0.5 mg/kg IV and 2.5 mg/kg PO. Furthermore, the Phase II study has proved betrixaban as an oral fXa inhibitor for prevention of venous thromboembolic events [1].

配胶、上样、跑胶、半干转无特殊,半干转后,就用TBST浸润一下后放入封闭液(试过5%牛奶、5%BSA)2小时,后取出直接抗体孵育(目标蛋白抗体1:1000、1:1500、1:2000【建议浓度1:1000-3000】,二抗1:2000、1:3000、1:5000【建议浓度1:1000-5000】,内参beta-actin差不多,目标蛋白4度过夜,内参室温2小时),孵育完后,TBST洗三次,每次10min,后二抗孵育,完后同样TBST洗三次,每次10min,后进行ECL发光液浸润2min,暗室压片2min(主要问题是在暗室中可以看到整张PVDF膜都有荧光,郁闷),显影定影,结果在胶片PVDF膜位置很黑,虽然可以见到我的条带,但是无法使用,不知道究竟怎样解决?(实验室另一位同学不存这样的问题)
试过几次都是同样的问题,是封闭的不好?抗体稀释度不够?TBST洗得不好?ECL发光步骤问题?渴求园里战友指导,谢谢!
