Catalase (CAT) Activity Assay Kit

Cat. Num. AAA9718961

• Synonyms: Catalase (CAT); Catalase (CAT) Activity Assay Kit; CAT assay kit

• Sequence Length: 527

• Application Notes: Catalase Activity Assay Kit provides a simple and easy colorimetric assay for the study of catalase activity in a variety of biological samples such as cell and tissue lysates or biological fluids. This assay kit utilizes the peroxidatic function of catalase for measuring catalase activity, based on the reaction of catalase with methanol, with the presence of an optimal concentration of H2O2. The formaldehyde produced can be measured colorimetrically at OD 540 nm. Therefore, the catalase activity present in the sample is proportional to the signal obtained.
• Preparation and Storage: Store at -20 degree C and keep from light immediately upon receipt. Kit has a storage time of 6 months from receipt. Refer to list of materials supplied for storage conditions of individual components.

Hydrogen peroxide is highly deleterious to the cell and its accumulation will cause oxidation of cellular targets such as DNA, proteins, and lipids, thus leading to mutagenesis and cell death. Removal of the hydrogen peroxide (H2O2) from cells by using catalase provides protection against oxidative damage to the cell. The role of catalase in oxidative stress related diseases has been widely studied. Catalase also demonstrates peroxidatic activity, in which low molecular weight alcohols can serve as electron donors. Aliphatic alcohols are specific substrates for catalase, however, other enzymes with peroxidatic activity do not utilize these substrates.

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]
