I.U.B.: 1.11.1.7

Peroxidase (HRP) is a hemoprotein catalyzing the oxidation by hydrogen peroxide of a number of substrates such as ascorbate, ferrocyanide, cytochrome c and the leuco form of many dyes. HRP has a molecular weight of 40 kDa and an optimum pH of 7.0. Stability: HPOFF is stable for 9-12 months at 2-8°C. HPOD is stable 2 to 3 years at 2-8°C.

Unit Definition: One Worthington Unit decomposes 1µmole of H2O2 per minute at 25°C, pH 7.0 using aminoantipyrine and phenol.
