The Total Antioxidant Capacity (T-AOC) Assay Kit (FRAP) is widely used to measure the overall antioxidant capacity of biological samples, such as serum, plasma, tissues, and plant extracts. It is particularly valuable in research focused on oxidative stress and its impact on health. By quantifying the ability of antioxidants to reduce ferric ions to ferrous ions, this kit helps assess the protective effects of antioxidants against free radicals. It is commonly applied in studies related to aging, chronic diseases, and the evaluation of antioxidant-rich foods or supplements. Additionally, it aids in understanding the efficacy of therapeutic interventions aimed at reducing oxidative damage in various conditions.
