Beschreibung

General description

o-Phenylendiamindihydrochlorid (OPD) ist ein chromogenes Substrat, das in Enzyme-linked-Immunosorbent-Assay(ELISA)-Verfahren eingesetzt werden kann, da es Meerrettichperoxidasekonjugate nutzt. Das Substrat produziert ein lösliches Endprodukt mit orange-brauner Farbe, das bei 450 nm spektrofotometrisch gemessen werden kann. Die OPD-Reaktion kann mit 3 N HCl oder 3 mol/l H2SO4 gestoppt und bei 492 nm gemessen werden.

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

Packaging

16 mg total tablet weight

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.
