Descrição geral

O dicloridrato de o-fenilenodiamina (OPD) é um substrato cromogênico que pode ser usado em procedimentos de ensaio de imunoabsorção enzimática (ELISA), pois utiliza conjugados de peroxidase de rábano. O substrato gera um produto final solúvel de cor laranja-marrom e pode ser lido por espectrofotometria em 450 nm. A reação de OPD pode ser interrompida com HCl 3N ou H2SO4 3 M e lida a 492 nm.

Aplicação

o-Phenylenediamine dihydrochloride has been used:
  • as a substrate for the eosinophil peroxidase (EPO) assay in bronchoalveolar lavage fluid (BALF)
  • in cell adhesion molecule-enzyme immunoassay (CAM-EIA) to analyze the amounts of E-selectin induced by test compounds (LPS or solutions and materials) on endothelial cells
  • in ultra-sensitive enzyme-linked immunosorbent assay (ELISA) to measure prolactin and luteinizing hormone (LH)

Reconstituição

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.
