Related Product Information for CAT active protein

Catalase (CAT) is an antioxidant enzyme present in all aerobic organisms. It isknown to catalyze H2O2 into water and oxygen in an energy-efficient manner in thecells exposed to environmental stress. H2O2 will have specific absorbance at 240nm. when will add CAT the absorbance wil decrease, thus the activiy of CAT can be measured by caculating H2O2 absorbance decrease. The reaction was performed in adding 10ul (dilute with 50mM Potassium Phosphate Buffer, pH7.0)recombinant human CAT to 290ul substrate mixture solution(50mM Potassium Phosphate Buffer, pH7.0, 0.036% H2O2 ,allow the substrate to equilibrate to 25 degree C), quickly mixed, then record the time required for the A240 to decrease from 0.45 to 0.40 absorbance units. One unit of catalase will decompose 1.0umole of H2O2 per minute at pH7.0 at 25 degree C. The activity of recombiant human CAT is 2000U/mg.

NCBI Description

This gene encodes catalase, a key antioxidant enzyme in the bodies defense against oxidative stress. Catalase is a heme enzyme that is present in the peroxisome of nearly all aerobic cells. Catalase converts the reactive oxygen species hydrogen peroxide to water and oxygen and thereby mitigates the toxic effects of hydrogen peroxide. Oxidative stress is hypothesized to play a role in the development of many chronic or late-onset diseases such as diabetes, asthma, Alzheimer's disease, systemic lupus erythematosus, rheumatoid arthritis, and cancers. Polymorphisms in this gene have been associated with decreases in catalase activity but, to date, acatalasemia is the only disease known to be caused by this gene. [provided by RefSeq, Oct 2009]
