D-Val-Leu-Lys-pNA (hydrochloride)

D-Val-Leu-Lys-pNA is a colorimetric substrate for plasmin. Plasmin binds and hydrolyzes D-Val-Leu-Lys-pNA to release p-nitroanilide (pNA), which can be quantified by colorimetric detection at 405 nm as a measure of plasmin activity.Formal Name: D-valyl-L-leucyl-N-(4-nitrophenyl)-L-lysinamide, dihydrochloride.
