Description

H-D-Phe-Pip-Arg-pNA (S-2238), 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 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 is sensitive, accurate, and easy to perform[1][2].—–C27H36N8O5—-[1]Goodnight SH Jr, et al.
