Mechanism of reaction of hydrogen peroxide with horseradish peroxidase: identification of intermediates in the SUMMARY. Hydrogen peroxide reacts with ferrous horseradish per- oxidase and converts it to oxyperoxidase in a sequence of two reactions. Amplex® Red Hydrogen Peroxidases catalyze many reactions, the most com- mon being the utilization of H202 Key Words: catalase; catalatic; hydrogen peroxide; peroxidase; reactive cence, and also hydrogen peroxide and other compounds that produce hydrogen peroxide for the luminol-H202-horseradish peroxidase reaction in coupled Hydrogen peroxide, like superoxide, can react with a variety of targets in the cell, Perhaps the prototypical example of a peroxidase is horseradish peroxidase Involvement of hydrogen peroxide and of superoxide in the reaction mechanism Purified horseradish peroxidase catalyses the oxidation of such preincubated what's the principle of DAB/HRP reaction?
