JC-1 (iodide salt)
JC-1 (5,5′,6,6′-Tetrachloro-1,1′,3,3′-tetraethylbenzimidazolylcarbocyanine, iodide) is a mitochondrial dye that stains mitochondria in living cells in a membrane potential-dependent fashion. JC-1monomer is in equilibrium with so-called J-aggregates, which are favored at higher dye concentration or higher mitochondrial membrane potential.
