h-d-phe-pip-arg-pna

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

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

H-D-Phe-Pip-Arg-pNA dihydrochloride (S-2238 dihydrochloride), a chromogenic substrate, mimics the N-terminal fragment of the A alpha chain of fibrinogen, the native substrate of thrombin. Specifically designed for thrombin detection, it is employed for quantifying antithrombin-heparin cofactor (AT-III) and is characterized by its sensitivity, accuracy, and ease of implementation.

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 is specific to thrombin and is used for quantifying antithrombin-heparin cofactor (AT-III), enabling a sensitive, accurate, and straightforward AT-III assay.
