RedoxSensor Red CC-1 is a unique probe whose fluorescence localization appears to be based on a cell's cytosolic redox potential. Upon passively entering live cells, the stain is either oxidized in the cytosol to a red-fluorescent product (excitation/emission maxima ~540/600 nm), which then accumulates in mitochondria, or the probe is transported to lysosomes, where it is subsequently oxidized. The differential distribution of the oxidized product appears to depend on the redox potential of the cytosol.
