ADHP is a non-fluorescent and highly sensitive and stable hydrogen peroxide probe. Experimentally used as a peroxidase fluorogenic substrate in the presence of HRP, a 1:1 stoichiometric reaction with hydrogen peroxide occurs, generating highly fluorescent resorufin. With absorption and fluorescence emission maxima at around 563 nm and 587 nm respectively, ADHP offers versatility in assay methods. Its high extinction coefficient of 54,000 cm-1M-1 enables the assay to be conducted using either fluorometric or spectrophotometric techniques.
