p nitrophenol is the substrate of choice for use with alkaline phosphatase in ELISA procedures. This substrate produces a soluble end product that is yellow in color and can be read spectrophotometrically at 405 nm. The pNPP reaction may be stopped with 3 M NaOH and read at 405 nm.
p-nitrophenol is suitable for use as a substrate for alkaline and acid phosphatase.
Typically a pNPP concentration of 1 mg/ml is used
Soluble in water.
