2020年8月29日 · Oxygen Radical Absorbance Capacity Assay Description: The ORAC assay measures a compounds ability to scavenge a free radical from ABAP compared to that Trolox.
G-Biosciences’ ORAC assay depends on the free radical damage to a fluorescent probe, such as fluorescein, to result in a change of fluorescent intensity and the degree of change is indicative of the amount of radical damage. The presence of antioxidants results in an inhibition in the free radical damage to the fluorescent compound.
