General description
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 chromogenic substrate in indirect enzyme-linked immunosorbent assay (ELISA) to detect immunoglobin G (IgG) antibodies against certain recombinant antigens/proteins
- as a streptavidin-horseradish peroxidase (HRP) substrate sandwich ELISA to analyze human interleukin (IL)-17A, IL-23, and IP-10
- as a substrate in ELISA for determination of IgG-class antibodies to Mycobacterium bovis in serum

Preparation Note
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.

Large repertoires of peptides displayed on bacteriophage have been extensively used to select for ligand-binding molecules. This is a relatively straightforward process involving several cycles of selection against target molecules, and the resulting ligands can be tailored to various applications.
