The TPTZ-Fe reaction is used in the ferric reducing antioxidant power (FRAP) assay to measure the antioxidant capacity of a substance. In this reaction, the TPTZ reagent (2,4,6-tripyridyl-s-triazine) reduces the ferric ion (Fe3+) to ferrous ion (Fe2+), resulting in a colored product that can be quantified spectrophotometrically. The intensity of the color formed is directly proportional to the antioxidant power of the substance being tested.
To make FRAP (Ferric Reducing Antioxidant Power) reagent, mix 25 ml of acetate buffer, 2.5 ml of TPTZ solution, and 2.5 ml of FeCl3 solution. Store the reagent in a dark container at 4°C until needed.
