D-Pro-Phe-Arg-pNA is a colorimetric substrate for plasma kallikrein. Plasma kallikrein preferentially binds to and cleaves the D-Pro-Phe-Arg (PFR) peptide sequence to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of plasma kallikrein activity. | [Uses]
D-Pro-Phe-Arg-pNA hydrochloride is the substrate for thrombin-like enzyme, with Km of 50.7 μM[1]. | [References]
