General description

Ferric Reducing Antioxidant Power (FRAP) is a measure of antioxidant capacity quantified by the antioxidant′s potential to reduce ferric iron (III) to ferrous iron (II). Antioxidants protect cells from damage by reactive oxygen species that are produced by oxidation reactions. As oxidative stress contributes to the development of many diseases including Alzheimer′s disease, Parkinson′s disease, diabetes, rheumatoid arthritis and neurodegeneration, the use of antioxidants in pharmacology is intensively studied. Antioxidants are also widely used as dietary supplements and as preservatives in a wide range of products such as food, cosmetics, rubber and gasoline.

Features and Benefits

  • Linear detection range: 0.5 to 180 µM Fe3+ reduction potential
  • Compatible with high-throughput handling systems.
  • The optimized formulation has greatly enhanced reagent and signal stability.

Suitability

The kit is suitable for the determination of ferric reduction antioxidant potential in plant extracts, foods, vitamins, supplements, and biological samples such as serum, plasma, and urine.

Principle

The Ferric Reducing Antioxidant Power (FRAP) Assay Kit measures antioxidant potential in which Fe3+ is reduced by antioxidant to Fe2+. The resulting Fe2+ specifically forms a colored complex with a chromogen. The color intensity at 590 nm is proportional to FRAP in the sample.
