Description: Thermo Scientific™ Pierce PNPP Substrates are powders, tablets, solutions and complete kits of p-nitrophenyl phosphate, a colorimetric, soluble substrate of alkaline phosphatase for use in ELISA applications

PNPP (p-Nitrophenyl Phosphate, Disodium Sal) is a widely used substrate for detecting alkaline phosphatase in ELISA applications. When alkaline phosphatase and PNPP are reacted, a yellow water-soluble reaction product is formed. This reaction product absorbs light at 405 nm. Pierce PNPP is available in four formats: dry crystalline powder, single-use tablets, a stable substrate solution, and a complete kit containing substrate solution and diethanolamine buffer.
