bz iegr pna (acetate)

Bz-IEGR-pNA is a colorimetric substrate for Factor Xa.1 Factor Xa preferentially binds to and cleaves the Ile-Glu-Gly-Arg (IEGR) peptide sequence to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of Factor Xa activity.References1.

N-(p-Tosyl)-GPR-pNA acetate is a colorimetric substrate for thrombin that can act as a measure of thrombin activity.

N-p-Tosyl-Gly-Pro-Lys-pNA is a colorimetric substrate for plasmin.1,2,3Plasmin binds and hydrolyzes N-p-tosyl-Gly-Pro-Lys-pNA to releasep-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of plasmin activity. 1.Jespersen, J., Gram, J., and Astrup, T.The autodigestion of human plasmin follows a bimolecular mode of reaction subject to product inhibitionThromb.

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.

Bz-D-Arg-pNA hydrochloride is a competitive inhibitor of trypsin.
