Description
OverviewA cell-permeable, chemically-reduced ethidium derivative. Commonly used to analyze respiratory burst in phagocytes. Useful fluorogenic probe for the detection of reactive oxygen species (ROS). It undergoes significant oxidation in resting leukocytes, possibly through the uncoupling of mitochondrial oxidative phosphorylation. Cytosolic dihydroethidium displays blue fluorescence, whereas after oxidation of this probe to ethidium, it intercalates cell’s DNA, staining the nucleus with a bright red fluorescence.

DescriptionA cell-permeable, chemically reduced ethidium derivative that can be used as a fluorogenic probe for the detection of reactive oxygen species (ROS). It undergoes significant oxidation in resting leukocytes, possibly through the uncoupling of mitochondrial oxidative phosphorylation. Cytosolic dihydroethidium displays blue fluorescence, however, following oxidation to ethidium and subsequent intercalation to DNA, a bright red fluorescence is achieved. Often used to determine the level of superoxide anion in cells by flow cytometry.
