S 2238 is a chromogenic substrate for thrombin that is used in amidolytic assay.

H-D-Phe-Pip-Arg-pNA dihydrochloride (S-2238 dihydrochloride )是一种显色底物，模仿了纤维蛋白原Aα链N端片段，即凝血酶的天然底物。H-D-Phe-Pip-Arg-pNA dihydrochloride 专为凝血酶检测而设计，用于抗凝血酶-肝素辅因子(AT-III)的定量。利用该底物的AT-III检测方法以其灵敏度、准确性和实施的便捷性而特别闻名。

H-D-Phe-Pip-Arg-pNA (S-2238) acetate is a chromogenic substrate designed based on the N-terminal fragment of the A alpha chain of fibrinogen, which is the physiological target of thrombin. As a specific indicator of thrombin activity, H-D-Phe-Pip-Arg-pNA acetate is utilized to quantify. This assay, utilizing H-D-Phe-Pip-Arg-pNA acetate, ensures high sensitivity, accuracy, and ease of execution.

H-D-Phe-Pip-Arg-pNA hydrochloride, a chromogenic substrate, mimics the N-terminal segment of the A alpha chain of fibrinogen, the native substrate of thrombin. It displays specificity towards thrombin and is employed for quantifying antithrombin-heparin cofactor (AT-III). The utilization of H-D-Phe-Pip-Arg-pNA hydrochloride in the AT-III assay enables a sensitive, accurate, and straightforward measurement process.
