Applicazioni

o-Phenylenediamine Free Base is a peroxidase substrate suitable for use in ELISA procedures. The substrate produces a soluble end product that is orange-brown in color and can be read spectrophotometrically at 450 nm. The OPD reaction may be stopped with 3 N HCl or 3 M H2SO4 and read at 492 nm.
o-Phenylenediamine has been used to detect transforming growth factor (TGF-β) and to measure anti-cTfRMAb-ScFv fusion protein using enzyme linked immunosorbent assay (ELISA).

Azioni biochim/fisiol

o-Phenylenediamine (o-PD) is a potent substrate for spectrophotometric horseradish peroxidase (HRP)-mediated enzyme-linked immunosorbent assay (ELISA), which gives 2,3-diaminophenazine (DAP) as a product of o-PD oxidation.

Ricostituzione

Dissolve one tablet in 0.05 M phosphate-citrate buffer, pH 5.0, to the desired concentration (typically an OPD concentration of 0.4 mg/ml is used). Add 40 μl of fresh 30% hydrogen peroxide per 100 ml of substrate buffer solution, immediately prior to use. Tablets are individually packaged in foil packets.

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.
