Background:
4-Nitrophenyl phosphate (pNPP) is a chromogenic substrate for alkaline phosphatase.1Upon hydrolysis by alkaline phosphatase, 4-nitrophenol is released, which can be quantified by colorimetric detection at 405 nm as a measure of alkaline phosphatase activity. It has been commonly used in ELISAs.
