XOD)through the chromogenic reaction of 4-aminoantipyrine(AAP),phenic acid(PA)and hydrogen peroxide(H2O2),which was produced via the oxidation of xanthine catalyzed by XOD,under the help of horseradish peroxidase( HRP) was proposed. The influences of temperature、pH and amount of substrate on th...
Signal Guard™ HRP reaction stopping reagent HRP coupling reactions provide sensitive biomolecular assays based on hydrogen peroxide- generating enzyme systems linked to peroxidase- mediated oxidation. Fluorogenic HRP substrates are preferred to use for enhancing assay sensitivities. Among them, the most ...

hydrogen peroxide biosensorHorseradish Peroxidaseelectrochemical methodAn amperometric biosensor for H2O2 detection was developed with immobilization of Horseradish Peroxidase (HRP) on Ag nanowires (AgNWs). Ag nanowires(AgNWs) have been prepared by the reductive deposition method and characterized by the ...
The catalytic reaction of HRP requires substrate hydrogen peroxide (H2O2) and hydrogen donor (DH2). Hydrogen donors are mostly colorless and prototype A reactive dye (D) that is colored by reaction. The process of enzymatic reaction is as follows: HRP DH2H2O2 -- to D2H2O There are many ...
