NAO is a green fluorescent mitochondrial dye whose staining is not dependent on mitochondrial membrane potential (1), unlike JC-1 (70011) or Rhodamine 123 (70010). NAO has been used to study multidrug resistance (2) and to measure changes in mitochondrial mass during apoptosis (3). The dye is reported to bind cardiolipin, a phosphoprotein in the inner mitochondrial membrane (4). Also see our MitoView™ Dyes and other mitochondrial dyes.
