The D-Glucose Assay Kit (Megaplex Red) provides a simple robust method for the measurement of D-glucose. This kit utilises a highly sensitive Megaplex Red probe which when coupled to horseradish peroxidase (HRP) and glucose oxidase (GOX) enzymatic reactions, allows for the measurement of D-glucose 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 between 530-560 nm and emission at ~ 590 nm* or colourimetrically at 570 nm.
*The excitation and emission maxima of Megaplex Red are 570 nm and 585 nm respectively.
