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.
Display all assay test kits available.
Fluorometric/UV method for the determination of H2O2 content in a variety of samples.
Advantages
- Simple format
- Very competitive price (cost per test)
- Ability to run in fluorescence or absorbance mode
- User friendly – Detailed protocol provided for the creation of calibration curve and the calculation of concentration in fluorescence mode. Single point standard for quicker and simpler analysis in absorbance mode.
- Mega-Calc™ software tool is available from our website for hassle-free raw data processing
- Suitable for manual, microplate and auto-analyser formats
- All reagents stable for > 2 years
