JC-1 (chloride salt)



Product Description

JC-1 (5,5′,6,6′-Tetrachloro-1,1′,3,3′-tetraethylbenzimidazolylcarbocyanine chloride) is a mitochondrial dye that stains mitochondria in living cells in a membrane potential-dependent fashion.

JC-1 monomer is in equilibrium with so-called J-aggregates, which are favored at higher dye concentration or higher mitochondrial membrane potential. The monomer JC-1 has green fluorescence (λ Em = 527 nm),while the J-aggregates have red fluorescence (λ Em = 590nm). Therefore, it is possible to use the fluorescence ratio technique to study mitochondrial membrane potentials. JC-1 is particularly useful for apoptosis studies. In apoptotic cells, the dye stays in the cytoplasm and fluoresces green. It has also been used in high throughput drug screening applications.

JC-1, iodide (#70014) is the original salt form of the dye. Biotium developed JC-1 chloride salt for applications where iodide ion is not desired. JC-1 chloride may also have the advantage of being slightly more water soluble than the iodide salt.
