The hydrogen peroxide Assay Kit provides a simple robust method for the measurement of hydrogen peroxide. This kit utilizes a highly sensitive Megaplex Red probe which in the presence of horseradish peroxidase (HRP), allows for the measurement of H2O2 in a sample. Upon oxidation of the probe by HRP, a coloured product (resorufin) is formed that can be measured in fluorescence mode using excitation in the range 530-560 nm and emission at ~ 590 nm or colourimetrically at 570 nm. The excitation and emission maxima of Megaplex Red are 571 nm and 585 nm respectively.
