Description générale

Le dichlorhydrate d'o-phénylènediamine (OPD) est un substrat chromogène qui peut être employé dans des techniques ELISA ("Enzyme-Linked Immunosorbent Assay", dosage par immunosorbant lié à une enzyme) puisqu'il utilise des anticorps conjugués à la peroxydase de raifort. Ce substrat donne un produit final brun orangé soluble, mesurable par spectrophotométrie à 450 nm. La réaction de l'OPD peut être arrêtée par l'ajout d'HCl 3 N ou d'H2SO4 3 M, puis mesurée à 492 nm.
o-Phenylenediamine dihydrochloride (OPD) is a chromogenic substrate that can be used in enzyme-linked immunosorbent assay (ELISA) procedures as it utilizes horseradish peroxidase conjugates. The substrate produces a soluble end product that is orange-brown 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 dihydrochloride has been used as a stop solution for evaluating bovine serum albumin (BSA) antibodies via enzyme-linked immunosorbent assay (ELISA). It has also been used to measure specific antibodies in pig serum by ELISA.

Caractéristiques et avantages

Supplied as 50 or 100 tablets per box, individually wrapped with foil for easy storage, use, and safety.

Reconstitution

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.
