Biochem/physiol Actions

p-Nitrophenyl phosphate (pNPP) is the substrate of choice for use with alkaline phosphatase in enzyme linked immunosorbent assay (ELISA) procedures. It is the substrate of choice in alkaline phosphatase systems due to its high sensitivity. This substrate produces a soluble end product that is yellow in color and can be read spectrophotometrically at 405 nm. This product is tested for use in cell culture applications. 4-nitrophenyl phosphate (pNPP), a small-molecule substrate can be used to study on alkaline phosphatases, acid phosphatases etc.^[1]
