      Detection principle

      A variety of antioxidant macromolecules, antioxidant molecules and enzymes in a system can eliminate all kinds of reactive oxygen species and prevent oxidative stress induced by reactive oxygen species. The total level reflect the total antioxidant capacity in the system. Many antioxidants in the body can reduce Fe3+ to Fe2+ and Fe2+ can form stable complexes with phenanthroline substance. The antioxidant capacity (T-AOC) can be calculated by measuring the absorbance at 520 nm.

      Dilution of sample

      It is recommended to take 2~3 samples with expected large difference to do pre-experiment before formal experiment and dilute the sample according to the result of the pre-experiment and the detection range (0.62-190.43 U/mL).

      The recommended dilution factor for different samples is as follows (for reference only):

      Sample type

      Dilution factor

      Human serum


      Human urine


      10% Rat liver tissue homogenate


      10% Epipremnum aureum tissue homogenate


      HepG2 cells


      HepG2 cell culture supernatant


      Note: The diluent is normal saline (0.9% NaCl) or PBS (0.01 M, pH 7.4).
