Description
- General description: o-Phenylenediamine (OPD) Free Base is a peroxidase substrate suitable for use in enzyme linked immunosorbent assay (ELISA) procedures. The substrate produces a soluble product that is orange-brown in color 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 has been used in the microtiter?based assay for hyaluronan quantification.[1] It has also been used in enzyme linked immunosorbent assay (ELISA) for color development.[2][3]
- Caution: May darken in storage.
