本品为凝血酶(Thrombin,Factor IIa)特异性比色发色底物,序列模拟纤维蛋白原 Aα 链 N 端天然底物结构。被凝血酶特异性切割后释放对硝基苯胺(pNA),在 405 nm 处产生黄色特征吸光度,吸光度变化与凝血酶活性成正比,可用于定量检测。

This product is a colorimetric chromogenic substrate highly specific for Thrombin (Factor IIa). Its sequence mimics the N-terminal fragment of the Aα chain of fibrinogen, the natural substrate of thrombin. Upon specific cleavage by thrombin, it releases p-nitroanilide (pNA), producing a characteristic yellow absorbance at 405 nm. The absorbance change is proportional to thrombin activity, enabling quantitative measurement.
