JC-1 solid | Sigma-Aldrich
Application The cyanine dye JC-1 has been used to determine mitochondrial transmembrane potential.. A dual-emission potential-sensitive probe that can be used to measure mitochondrial membrane potential. JC-1 is a green-fluorescent (λ ex 520 nm) monomer at low membrane potential. At higher potentials, JC-1 forms red-fluorescent (λ em 596 nm ) "J-aggregates," which exhibit broad excitation ...
