  • High sensitivity detection of peroxidase activity
    Patent number: 5079150
    Abstract: A new class of peroxidase substrates consists of o-diaminobenzenes having a substituent in the 4 position. The new substrates may be used in immunoassays in which a peroxidase is the label, or in assays for the peroxidase itself. Immunoassays using other enzyme labels which cause formation of hydrogen peroxide may be followed using the substrate of the invention by adding the substrate and a peroxidase to the assay fluid and detecting color formed as a result of oxidation of the substrate by the formed peroxide.
