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.

96 wells (1 kit) - ELISA is a sandwich enzyme immunoassay for the quantitative measurement of Bone-specific Alkaline Phosphatase (BAP).

Supplier: Invitrogen

Stop Solution is 0.16M sulfuric acid for use with the ELISA substrate 3,3’,5,5’ - tetramethylbenzidine (TMB). In the presence of horseradish peroxidase (HRP) enzyme conjugates, TMB and peroxide react to produce a blue byproduct having maximum absorbance at 605nm. The color intensity is proportional to the amount of HRP activity, which in turn is related to the levels of target analyte in an optimized ELISA procedure. Addition of sulfuric acid stop solution changes the color to yellow (absorbance maximum at 450nm), stabilizing the color development to enable accurate measurement of the intensity at 450nm using a spectrophotometer or plate reader.
