Horseradish peroxidase

Horseradish peroxidase (HRP) catalyzes the conjugation of phenol and aniline derivatives in the presence of hydrogen peroxide. HRP catalyzes the conversion of chromogenic substrate (e.g. TMB, DAB, ABTS) into colored products, and produces light when acting on chemiluminescent substrates.
