Catalase (CAT) Activity Assay Kit

Detection principle

The reaction that catalase (CAT) decomposes H2O2 can be quickly stopped by ammonium molybdate. The residual H2O2 reacts with ammonium molybdate to generate a yellowish complex. CAT activity can be calculated by production of the yellowish complex at 405 nm.

Performance characteristics

The activity of CAT increased at the beginning of the UV exposure until 80 mJ/cm2, then decreased with the UV fluence reached 120 mJ/cm2. The induced CAT activity was higher in the UV/Cl2 process (purple) compared with that of the UV alone process.

Q Wan et al investigate the efficiency and mechanism of fungal spore disinfection using UV-LEDs irradiation and chlorine. Catalase (CAT) activity of fungal spore was determined using CAT activity assay kit (E-BC-K031-M).

Dilution of sample

It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (1.12 -150 U/mL).

The recommended dilution factor for different samples is as follows (for reference only):

Note: The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4).
