Description

ABTS is a radical cation and a peroxidase substrate. It is used to assess antioxidant capacity in the Trolox equivalent antioxidant capacity (TEAC) assay. It is blue in the presence of sodium persulfate or metmyoglobin but decolorizes upon incubation with antioxidants, and the antioxidant capacity can be determined spectrophotometrically. ABTS has also been used as an enzyme substrate in ELISAs. Upon incubation with a peroxidase, it produces a soluble green product that can be quantified by colorimetric detection at 405 nm.
