Horseradish peroxidase (HRP)

Horseradish peroxidase (HRP) is the most commonly used antibody-conjugated enzyme. Substrates for HRP are luminol and benzidine substrates. Tetramethylbenzidine (TMB) and similar substrates are oxidized by HRP in the presence of hydrogen peroxide, or nontoxic substitutes, to yield a chinoid structure of intense blue color.Product SpecificationsHorseradish peroxidase (HRP) PeroxidaseMOLECULAR BIOLOGY GRADEMW: approximately 40,000 g/mol
