JC-1
5,5,6,6-Tetrachloro-1,1,3,3-tetraethylbenzimidazolylcarbocyanine iodide; CAS#: 3520-43-2
JC-1 is a green-orange fluorescent dye used to assay mitochondrial membrane potential for studying cell health in flow cytometry applications.
Mechanism and principle
JC-1 (5,5,6,6’-tetrachloro-1,1’,3,3’ tetraethylbenzimi-dazoylcarbocyanine iodide) is a cationic dye that selectively labels mitochondria in live cells. In response to increases in mitochondrial transmembrane potential (ΔΨM), from approximately 80 to 100 mV, the dye changes color from green to orange. The mechanism for this is the reversible formation of JC-1 aggregates upon membrane polarization; high membrane potential results in JC-1 monomer aggregation into J aggregates. These J aggregates exhibit orange fluorescence, while JC-1 monomers fluoresce green. By monitoring the intensity and ratios of green/orange fluorescences, JC-1 staining can be used as an assay for mitochondrial membrane potential.Excitation and emission
Under low mitochondrial membrane potential conditions, JC-1 molecules exist largely as monomers. These have an absorption peak of 510 nm and an emission peak of 527 nm. Under polarized conditions (high ΔΨM), J aggregates form, which have an absorption peak of 585 nm and an emission peak of 590 nm. Both JC-1 monomers (green form) and J aggregates (orange form) can be excited by a 488 nm argon laser. The JC-1 monomer green emission can be detected using the FL1 channel of a flow cytometer, while the J aggregate orange emission can be detected using the FL2 channel.Form | Mitochondria Membrane Potential | Color | Absorption (nm) | Emission (nm) | Emission Channel |
JC-1 monomer | Low | Green | 510 | 527 | FL1 |
J aggregate | High | Orange | 585 | 590 | FL2 |
JC-1 Alternatives
Although JC-1 is widely used in many labs, one problem it suffers from is poor water solubility. An alternative version, which addresses this issue, is JC-10.
