Rhodamine 123 (Rh123) is a cationic green-fluorescent xanthene dye used to monitor membrane polarization in mitochondria and bacteria in live cell assays.

The dye distributes according to the negative potential of the membrane. Loss of potential will result in loss of the dye and, therefore, the fluorescence intensity. Like TMRE, Rhodamine 123 can be used to study mitochondrial function changes and cell viability in response to stimuli or pharmaceuticals of interest.

Rhodamine 123 is also used as a tracer dye to determine the rate and direction of membrane transport.
