H-D-Phe-Pip-Arg-pNA (acetate)

H-D-Phe-Pip-Arg-pNA (S-2238) acetate, a chromogenic substrate, is patterned after the N-terminal portion of the A alpha chain of fibrinogen, which is the natural substrate of thrombin. H-D-Phe-Pip-Arg-pNA acetate is specific for thrombin and is used to measure antithrombin-heparin cofactor (AT-III) . The AT-III assay using H-D-Phe-Pip-Arg-pNA acetate is sensitive, accurate, and easy to perform[1][2].
