Dihydroethidium, also known as Hydroethidine and PD-MY 003, is a cell-permeable blue fluorescent dye. DHE-derived fluorescence at 570 nm is a convenient method for detection of intracellular and extracellular superoxide produced by phagocytic and vascular NADPH oxidase. Dihydroethidium is neuroprotective by reducing superoxide in mice after stroke.
