MitoTracker Deep Red FM

MitoTracker Deep Red FM is a deep red fluorescent dye for mitochondria that selectively accumulates within the mitochondrial matrix dependent on the mitochondrial membrane potential (Δψ) . It covalently binds to mitochondrial proteins by reacting with free thiol groups on cysteine residues. Following covalent binding, sensitivity to Δψ changes diminishes, though initial staining remains Δψ-dependent. The MitoTracker Deep Red FM probe is suitable for staining live cells or tissues, serving to label mitochondria and indirectly detect mitochondrial membrane potential alterations. Its maximum excitation/emission wavelengths are 644/665 nm (Storage: Protect from light) .
