o-Phenylenediamine dihydrochloride has been used:as a substrate for the eosinophil peroxidase (EPO) assay in bronchoalveolar lavage fluid (BALF)in cell adhesion molecule-enzyme immunoassay (CAM-EIA) to analyze the amounts of E-selectin induced by test compounds (LPS or solutions and materials) on endothelial cellsin ultra-sensitive enzyme-linked immunosorbent assay (ELISA) to measure prolactin and luteinizing hormone (LH)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.
