H-D-Phe-Pip-Arg-pNA hydrochloride

Description: 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.
