Alkaline phosphatase (ALP/AKP) activity assays are used to evaluate the hydrolytic capacity of samples toward phosphate monoesters. They are commonly applied in studies of osteogenic differentiation, bone metabolism, hepatobiliary injury, enzyme-labeled reactions, microbial metabolism, and ...
The value of p-nitrophenyl phosphate disodium salt (pNPP) in experimental work lies in its specific role within alkaline phosphatase (ALP) systems. It is one of the most classical soluble chromogenic substrates used in ALP reactions and has long been applied in serum ALP activity assays, ...
