Horseradish peroxidase (HRP) is a 40 kDa protein that catalyzes the oxidation of substrates by hydrogen peroxide to produce colored or fluorescent products or release light as a byproduct of the reaction. It is most commonly used in blotting, immunoassays and immunohistochemical methods.Pisum sativum lectin (PSA/PSL) is coupled to HRP in the appropriate ratio to provide optimal staining characteristics.
