Übersicht
p-Nitrophenyl phosphate is the most common substrate for alkaline phosphatase-based ELISA assays. Hydrolysis of the phosphate ester liberates p-nitrophenol, a soluble, yellow chromogen that can be measured spectrophotometrically at 405 nm (ε = 1.83 x 104 M-1cm-1). As the reaction is linear, kinetic assays can be performed. Endpoint determinations can also be performed by stopping the reaction with strong base and measuring the absorbance at 405 nm. This p-NPP preparation is a stable, convenient, liquid concentrate in a proprietary solvent.
p-Nitrophenyl phosphate supplied as a 50X concentrate (0.19 mol/l). For use with p-NPP Substrate Buffer, Cat. No. 487664.
Excellent substrate for alkaline phosphatase-based ELISA assays. Produces yellow soluble end product that can be read at 405 nm to 410 nm. Both kinetic and endpoint determinations can be performed. Supplied as ready-to-use. A ready-to-use diluent is available separately (Cat. No. 487664).
