Application

4-Nitrophenyl phosphate di(tris) salt has been used:
  • as a substrate to quantify tartrate-resistant acid phosphatase (TRAP) activity in cell lysates
  • to determine phosphatase activity using native polyacrylamide gel electrophoresis (PAGE)
  • for alkaline phosphatase in enzyme-linked immunosorbent assay (ELISA)

Biochem/physiol Actions

p-Nitrophenyl Phosphate (pNPP) is a preferred substrate for alkaline phosphatase in enzyme-linked immunosorbent assay (ELISA) procedures, because of its high sensitivity. This substrate produces a soluble yellow end-product and can be read spectrophotometrically at 405 nm.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
