Depiction of VeraTag™ technology. In both lysate and FFPE assays, one antibody conjugated to biotin and one antibody conjugated to a VeraTag™ reporter bind to their respective analytes. Streptavidin-functionalized sensitizer dye binds to Ab-biotin. 670 nm light causes singlet oxygen release, which induces cleavage and release of the VeraTag™ reporter molecule into illumination buffer (IB). IB is collected and analyzed by capillary electrophoresis. For details, see Materials and methods.
