Rat Catalase ELISA Kit

Cat. Num. AAA726781

• Reactivity: Rat
• Synonyms: Catalase; Rat Catalase ELISA Kit; CAT elisa kit

• Reactivity: Rat
• Specificity: This assay has high sensitivity and excellent specificity for detection of CAT. No significant cross-reactivity or interference between CAT and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between CAT and all the analogues, therefore, cross reaction may still exist in some cases.

• Samples: Serum, plasma, cell culture supernatants, body fluid and tissue homogenate
• Assay Type: Quantitative Competitive
• Sensitivity: 0.1 ng/mL
• Preparation and Storage: Store all reagents at 2-8 degree C.

Intended Uses: This CAT ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Rat CAT. This ELISA kit for research use only, not for therapeutic or test applications!

Principle of the Assay: CAT ELISA kit applies the competitive enzyme immunoassay technique utilizing a polyclonal anti-CAT antibody and an CAT-HRP conjugate. The assay sample and buffer are incubated together with CAT-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the CAT concentration since CAT from samples and CAT-HRP conjugate compete for the anti-CAT antibody binding site. Since the number of sites is limited, as more sites are occupied by CAT from the sample, fewer sites are left to bind CAT-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The CAT concentration in each sample is interpolated from this standard curve.

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]

Uniprot Description
