D-Val-Leu-Lys-pNA dihydrochloride  (Synonyms: D-Val-Leu-Lys-p-itoailide dihydrochloride; D-VLK-pNA dihydrochloride; S 2251 dihydrochloride)

D-Val-Leu-Lys-pNA dihydrochloride (D-VLK-pNA dihydrochloride) is a colorimetric substrate for plasminolytic activity. D-Val-Leu-Lys-pNA dihydrochloride is catalytically bound and hydrolyzed by plasmin to release p-nitroaniline (pNA), which can be detected colorimetrically at 405 nm as a measure of plasminolytic activity^[1].
