Horseradish peroxidase
Description
Horseradish peroxidase readily combines with hydrogen peroxide (H2O2) and the resultant [HRP-H2O2] complex can oxidize a wide variety of hydrogen donors.
Abbreviation: HRP
MitoPedia methods: Fluorometry
Application in HRFR
- HRP: Horseradish peroxidase (peroxidase from horseradish Type II, essentially salt-free, lyophilized powder, 150-250 units/mg solid); Sigma P 8250, store at 4 °C.
- The use of horseradish peroxidase type II in fluorometric measurement of peroxide production is recommended by Laszlo Tretter.
Reaction
- Donor + H2O2 → Oxidized Donor + 2 H2O
Known inhibitors
- According to Sigma-Adrich, citing [1]: sodium azide, cyanide, L-cystine,dichromate, ethylenethiourea, hydroxylamine, sulfide, vanadate, p-aminobenzoic acid, and Cd2+, Co2+, Cu2+, Fe3+, Mn2+, Ni2+, and Pb2+ ions.
