Webp-Nitrophenyl Phosphate (pNPP) is the preferred substrate of ALP-based microwell plate assays. In the presence of Alkaline phosphatase (ALP), pNPP is hydrolysed into p-nitrophenol and inorganic phosphate, which results in a yellow, soluble end product. The result is measured at 405 nm (kinetic assays). WebMany different substrates can be used for these assays with p-nitrophenyl phosphate (pNPP), fluorescein diphosphate (FDP), and 6,8-difluoro-4-methylumbellyferyl phosphate (DiFMUP) being the most efficient and versatile. Equally, larger molecules such as phosphotyrosyl peptides can also be used to mimic more natural substrates.
