Amplex Red is a non-fluorescent, highly sensitive and stable probe for H2O2. Amplex Red is a fluorogenic substrate for peroxidase. In the presence of horseradish peroxidase (HRP), the Amplex Red reagent reacts in a 1:1 stoichiometry with H2O2 to produce highly fluorescent resorufin. Because H2O2 is produced in many different enzymatic reactions, the Amplex Red reagent allows researchers to detect the activity of many different enzymes.
