Product description
The FRAP method is commonly used to detect the total antioxidant capacity of various body fluids such as plasma, serum, saliva, urine, lysates of cells or tissues, plant or herbal extracts, or various antioxidant solutions. In an acidic environment, antioxidants can reduce Fe3+-TPTZ to blue Fe2+-TPTZ, and the total antioxidant capacity of the sample can be obtained by measuring the blue Fe2+-TPTZ at 590nm.
