DPPH Antioxidant Capacity Assay Kit

Antioxidantsare molecules capable of slowing or preventing the oxidation of othermolecules. Endogenous and dietary antioxidants (such as, glutathione, vitamins)and antioxidant enzymes (such as catalase, glutathione peroxidase) protect cellsfrom reactive oxygen species. Antioxidant capacity measurements are widely usedin research, food, beverage, and nutraceutical testing.

Suitable for a variety of sample types, including food, beverages, and biological samples,

TheDPPH Antioxidant Capacity Assay Kit provides a simple, direct, colorimetricmethod to quantify total antioxidant capacity based on reduction of the stableradical DPPH, resulting in a decrease in absorbance at 517 nm. Results areexpressed relative to a Trolox standard.Thisassay detects approximately 11–300 µM Trolox equivalents.
