MitoSOX Red is a novel fluorescent probe that is specific and cell membrane-permeable and targets mitochondria in living cells.MitoSOX Red is oxidized by superoxide upon entry into the mitochondria and is not oxidized by other ROS or RNS-generating systems.MitoSOX Red then binds to nucleic acids in the mitochondrion and produces a strong red fluorescence.MitoSOX Red can be used as a fluorescent indicator for the specific detection of superoxide.MitoSOX Red can be used as a fluorescent indicator for the specific detection of superoxide. MitoSOX Red can be used as a fluorescent indicator to specifically detect superoxide. Superoxide dismutase (SOD) prevents the oxidation of MitoSOX Red.
