Application

Phosphatase substrate has been used as a substrate in tartrate-resistant acid phosphatase (TRAP) assay and alkaline phosphatase (ALP).
Chromogenic substrate for use with alkaline and acid phosphatase ELISA procedures. Produces a soluble end product that is yellow in color and can be read spectrophotometrically at 405 nm. The pNPP reaction may be stopped with 3 N NaOH and read at 405 nm.

Other Notes

Substrate for the determination of acid and alkaline phosphatases.

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.
