pNPP Substrate. p-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).
