D-Val-Leu-Arg-pNA is a colorimetric substrate for the serine protease glandular tissue kallikrein. Kallikrein is responsible for the regulation of blood pressure and activation of inflammation by releasing kinins (bradykinin and kallidin) from kinogens.
Activity is quantified by the release of p-nitroaniline which is measured by absorbance at 405 nm.
