ITEM #: 11557419
Disruption of the mitochondrial transmembrane potential is one of the earliest intracellular events that occur following induction of apoptosis. The MitoLight Apoptosis Detection Kit utilizes a lipophilic cation, termed as MitoLight, as a mitochondrial activity marker. MitoLight is a mitochondrial dye that stains mitochondria in living cells in a membrane potential-dependent fashion. The monomer is in equilibrium with so-called J-aggregates, which are favored at higher dye concentration or higher mitochondrial membrane potential. MitoLight partitions differently in healthy cells than in apoptotic cells. Therefore, it has been possible to use a fluorescence ratioing technique to study mitochondrial membrane potentials. In healthy cells, the dye accumulates and aggregates in the mitochondria, giving off a bright red fluorescence (lambdaem = 585-590 nm). In apoptotic cells with altered mitochondrial membrane potential, the dye in its monomeric form stays in the cytoplasm, fluorescing green (lambdaem = 527-530 nm), providing a ready discrimination between apoptotic and nonapoptotic cells. The fluorescence can be observed by fluorescence microscopy using a band-pass filter (detects FITC and rhodamine) or analyzed by flow cytometry using FITC channel for green monomers (E x /Em = 488/530) and PI channel for red aggregates (E x /Em = 488/585).
