JC-1 is a cationic carbocyanine dye that accumulates in the mitochondria of live cells in a potential-dependent manner.

The dye exists as a green-fluorescent monomer at depolarized membranes and low concentrations. At higher concentrations (aqueous solutions above 0.1 µM) and hyperpolarized membranes, the dye forms J-aggregates that exhibit an emission at the orange channel. The J-aggregates can be excited at 535 nm, and the monomeric form and aggregate together — at 475 nm.

Healthy cells have high mitochondrial membrane potential, and the decrease of mitochondrial membrane potential is a marker of the early stage of apoptosis. All this allows the use of changes in the orange/green fluorescence ratio of JC-1 to determine healthy vs. depolarized mitochondria. The orange/green fluorescence ratio of JC-1 depends only on the mitochondrial membrane potential and not on other factors such as the size, shape, and density of mitochondria.

MCF-7 human breast adenocarcinoma cells stained with LumiTracker® Mito JC-1 mitochondrial dye (2275-x, 1 µM, 10 min at 37°C) and imaged under a microscope at 510 and 575 nm. Cells were cultured in the presence of the protonophore carbonyl cyanide 3-chlorophenylhydrazone (CCCP, 15 μM, 24 h) and without it (control). Healthy cells are brightly fluoresce in the orange channel (fluorescence of J-aggregates) and weakly fluoresce in the green channel (fluorescence of dye monomers); cells with depolarized mitochondria have reduced fluorescence in orange and higher fluorescence in green channels.
