Description Antioxidants are a group of free radical scavengers, including macro and micro molecules (transferrin,
vitamin E, etc.) and enzymes (catalase, GSH reductase, etc.), that can protect vital cellular target against
oxidative attack from free radicals or reactive oxygen species (ROS). Due to the chemical diversity and
cooperative nature of antioxidants, the measurement of total antioxidant capacity (TAC) is important in
monitoring the clinical status of body fluids, as well as the cumulative capability of various food supplements
to counteract oxidative stress. The ScienCell Total Antioxidant Capacity (TAC) Assay is a cupric ion reducing
antioxidant capacity (CUPRAC) spectrophotometric method, which can simultaneously measure hydrophilic
and lipophilic antioxidants at physiological pH. Trolox, a cell-permeable, water-soluble derivative of vitamin E with antioxidant properties, serves as a standard.
Product Use This assay kit is used to evaluate total antioxidant capacity in vitro. It is for research use only. Not for use in
animals, humans, or diagnostic procedures.
