일반 설명

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.

애플리케이션

o-Phenylenediamine dihydrochloride has been used:
  • as a substrate in conventional capture enzyme-linked immunosorbent assay (ELISA) for recombinant hemagglutinin (rHA) protein detection
  • as a substrate for the determination of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) immunoglobulin G (IgG) antibodies by ELISA
  • as a colorimetric reagent specific for horseradish peroxidase (HRP) activity assessment in an ELISA protocol using SARS-CoV-2 antigens for S protein

재구성

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.
