Webradical absorbance capacity (ORAC) assay replaces phycoerythrin with fluorescein, which is much more stable over the time frame of the assay [7]. This assay has been automated [8] and over time converted to a microplate format [9]. Ronald Prior at Brunswick Laboratories and his colleagues have accomplished much of the development of the ORAC assay.
