Enzyme assays are fundamental to understanding biological processes, developing diagnostics, and advancing pharmaceutical research. Among the most crucial reagents in this field is Disodium 4-Nitrophenyl Phosphate (PNPP), a substrate widely employed to detect the activity of alkaline phosphatase (AP). PNPP (CAS 4264-83-9) is prized for its ability to undergo enzymatic hydrolysis, producing a quantifiable chromogenic signal. As a premier manufacturer and supplier of high-quality chemical intermediates, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing PNPP that meets the rigorous demands of modern scientific applications.

The mechanism is elegantly simple: alkaline phosphatase cleaves the phosphate group from PNPP, releasing p-nitrophenol. This molecule, under alkaline conditions, turns yellow and can be measured spectrophotometrically, typically at wavelengths around 405 nm. This colorimetric conversion allows researchers to accurately determine the presence and activity level of alkaline phosphatase in various biological samples. Whether in diagnostic kits, like ELISA, or in fundamental research for enzyme kinetics, the reliability of PNPP is paramount.
