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. This kit provides fast results after a quick 10 minute protocol, and it is suitable for use with serum, plasma, lysates, biological fluids, and purified food or drug extracts.
