Application

4-Nitrophenyl phosphate bis(tris) salt has been used to determine the enzyme activity of acid and alkaline phosphatase in cell lysates.

Biochem/physiol Actions

4-Nitrophenyl phosphate is a non-proteinaceous and non-specific chromogenic substrate, preferred for alkaline phosphatase (ALP) in enzyme-linked immunosorbent assay (ELISA). It is widely used to assay protein tyrosine phosphatases (PTPs). Upon cleavage, the substrate produces a yellow product that is spectrophotometrically measured.

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.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
