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/proteinsas a streptavidin-horseradish peroxidase (HRP) substrate sandwich ELISA to analyze human interleukin (IL)-17A, IL-23, and IP-10as a substrate in ELISA for determination of IgG-class antibodies to Mycobacterium bovis in serum应用:
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.
