Product Overview :
Antioxidants in the sample reduce dark blue-green colored ABTS radical to colorless reduced ABTS form. The change of absorbance at 660 nm is related with total antioxidant level of the sample. The assay is calibrated with a stable antioxidant standard solution which is traditionally named as Trolox Equivalent that is a vitamin E analog.
Compatible Sample Types :
Blood serum, plasma, semen plasma, saliva, urine, cell lysates, tissue homogenates, beverages, fruit juices and oils (oils require different reagent 1) can be used as sample.
