Beschreibung

Anwendung

4-Nitrophenyl phosphate bis(cyclohexylammonium) salt has been used as a component in the colorimetric reagent for abscisic acid (ABA) assay.

Biochem./physiol. Wirkung

p-Nitrophenyl phosphate (pNPP) is the preferred substrate for use with alkaline phosphatase in enzyme-linked immunosorbent assay (ELISA) procedures. Due to its high sensitivity, pNPP is the considered substrate in alkaline phosphatase systems. ELISA applications based on pNPP can be read in timed assays or delayed readings by stopping with alkaline solutions. This substrate yields a yellow-colored soluble end product that can be measured spectrophotometrically at 405 nm.
