Near-infrared (NIR)-FLIVO® Tracers are used in conjunction with NIR-FLIVO® Free Dye Control Assays. The NIR-FLIVO® Free Dye Control Assay uses the NIR-FLIVO® Free Dye Control reagent (*Dylight® 690 Free Dye). When injected, both the Free Dye Control and the Tracer reagents will generate a fluorescent signal, but only the Tracer should bind to active caspases and remain inside an apoptotic cell, while signal associated with the Free Dye Control represents background noise.
