BQC Redox - Model KF01004 | ORAC -Antioxidant Capacity Assay Kit

BQC ORAC Assay Kit is based on the inhibition of fluorescein oxidation by peroxyl radical in the presence of antioxidants. Peroxyl radical (ROO·) is produced by a free radical initiator (AAPH: 2,2’-azobis-2- methylpropanimidamide dihydrochloride) which produces a fluorescent quenching of fluorescein over time. The presence of antioxidants inhibits the free radical damage to fluorescein, resulting in a preservation of the fluorescent signal.
