General description
用于测定酸性和碱性磷酸酶的显色底物。该反应产生黄色的可溶性最终产物。可以用 3N NaOH 终止反应，并在 405nm 下读数。
Application
4-Nitrophenyl phosphate disodium salt hexahydrate has been used in enzyme-linked immunosorbent assay (ELISA) as a substrate for streptavidin-Alkaline Phosphatase. It has also been used as a substrate in control assay for comparing 4-aminophenyl phosphate/diethanolamine (APP/DEA) assay for alkaline phosphatase.
Biochem/physiol Actions
4-Nitrophenyl phosphate disodium salt hexahydrate (pNPP) is a non-proteinaceous and non-specific substrate for determining protein tyrosine phosphatase activity. Hydrolysis of pNPP yields p-nitrophenol. pNPP is a common chromogenic substrate for alkaline phosphatase.
