DiOC6(3),英文全名3,3-Dihexyloxacarbocyanine Iodide,CAS NO. 53213-82-4, DiOC6(3), a carbocyanine dye from the DiOC family, cannot be exclusive to the mitochondrial membrane potential measurement in intact cells, except by dissipating the plasmatic and ER membrane potentials as well as the DpH. DiOC6(3) is widely used as a cytofluorometric DCm indicator. To produce rigorous and reproducible results, the dye and the cell concentrations have to be monitored with care. When DiOC6(3) is used at low concentrations (10–20 nM), this dye rapidly reaches equilibrium in the mitochondria with low quenching effects. The use of higher concentrations (more than 50 nM) may result in non-mitochondrial staining (plasma membrane and endoplasmic reticulum) and in fluorescence quenching. Moreover, similar to probes previously mentioned, the use of relatively high concentrations of dye leads to a high accumulation in the inner mitochondrial membrane, resulting in a quenching of the fluorescence and, occasionally, in an inhibition of either mitochondrial respiration or complex I (except for TMRM and TMRE) (30). Many factors, such as the cell/dye ratio, cell size variability or the magnitude of plasma membrane potential may affect the fluorescence intensity of cells stained with DiOC6(3) (31). If the cell population studied is homogeneous and asynchronous, this potential pitfall is not of crucial interest; otherwise, internal standards and normalization procedures have to be used to allow the detection of DCm dissipation and DiOC6(3) fluorescence decrease (30).
