Allgemeine Beschreibung

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.
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.

Anwendung

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.

Leistungsmerkmale und Vorteile

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

Rekonstituierung

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.

Colorimetric Alkaline Phosphatase and Peroxidase Substrate Detection Systems

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
