General description

o-Phenylenediamine (OPD) Free Base is a peroxidase substrate suitable for use in enzyme linked immunosorbent assay (ELISA) procedures. The substrate produces a soluble product that is orange-brown in color and can be read spectrophotometrically at 450 nm. The OPD reaction may be stopped with 3N HCl or 3M H2SO4 and read at 492 nm.

Application

o-Phenylenediamine has been used in the microtiter?based assay for hyaluronan quantification. It has also been used in enzyme linked immunosorbent assay (ELISA) for color development.

Packaging

50, 100 g in glass bottle

Caution

May darken in storage.

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.
