Background:
PNPP is a non-proteinaceous chromogenic substrate for alkaline and acid phosphatases used in ELISA and conventional spectrophotometric assays.
Phosphatases catalyze the hydrolysis of PNPP liberating inorganic phosphate and the conjugate base of para-nitrophenol (pNP). The resulting phenolate is yellow, with a maximal absorption at 405 nm[1].
