Description

General description

Il s'agit d'un substrat chromogène permettant de doser les phosphatases acide et alcaline. La réaction donne un produit final soluble de couleur jaune. Elle peut être arrêtée par l'ajout de NaOH 3 N, puis mesurée à 405 nm.

Application

4-Nitrophenyl phosphate disodium salt hexahydrate has been used:

• as a component in diethanolamine buffer to detect alkaline phosphatase-conjugated antibodies in enzyme linked immunosorbent assay (ELISA)
• to treat adherent cells in adhesion assay
• as a phosphatase substrate in in vitro phosphatase assay in substrate buffer for ELISA

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.
