Description
Detection principle
ABTS is oxidized to green ABTS•+ by appropriate oxidant, which can be reduced to colorless ABTS in the presence of antioxidants. The TAS of the sample can be determined and calculated by measuring the absorbance of ABTS•+ at 660 nm. Trolox is an analog of VE and has a similar antioxidant state to that of VE. Trolox is used as a reference substance for total antioxidant status.

Images
TAS significantly decreased in diabetic model (DM), treatment of Cellgevity® significantly improved TAS. (**P<0.01, ***P<0.001)
O O Ogunlabi et al investigate the effects of Cellgevity® in diabetic model. Total antioxidants status (TAS) of rat serum was determined using TAS colorimetric assay kit (E-BC-K801-M).
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 (0.23-2 mmol Trolox Equiv. /L).
The recommended dilution factor for different samples is as follows (for reference only):
