OxiSelect™ Ferric Reducing Antioxidant Power (FRAP) Assay Kit is a quantitative assay for measuring the antioxidant potential within various samples. Following the reduction of ferric iron (Fe3+) to ferrous iron (Fe2+) by antioxidants present in the sample, the kit colorimetric probe develops a blue color that is read colorimetrically at 540-600nm. The antioxidant potential of samples is determined based on an iron standard curve and results are calculated at Fe2+ equivalents (µM) or FRAP value.
- Quick, 10 minute protocol
- Measures antioxidant potential in samples through the reduction of ferric iron (Fe3+) to ferrous iron (Fe2+)
- Detection sensitivity limit of approximately 2 µM Fe2+ iron equivalents
- Suitable for use with serum, plasma, lysates, biological fluids, and purified food or drug extracts
