Description: 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.

| Biological target: | Dihydroethidium (Hydroethidine; PD-MY 003) is a superoxide indicator; exhibits blue-fluorescence in the cytosol until oxidized, where it intercalates within the cell's DNA, staining its nucleus a bright fluorescent red (Ex/Em=518/616 nm). |
| In vitro activity: | Subsequently, the levels of reactive oxygen species, malondialdehyde, GPX4, SLC7A11 and Nrf2, which are indicators of ferroptosis, were measured by a dihydroethidium fluorescent dye probe, biochemical kit, western blotting and reverse transcription quantitative polymerase chain reaction. Reference: Front Immunol. 2022 Oct 19;13:967151. https://pubmed.ncbi.nlm.nih.gov/36341347/ |
| In vivo activity: | Furthermore, DHE (dihydroethidium) probe technology was used to analyze changes in ROS levels. The results showed that the ROS levels in the livers of the mice in the OXA group were increased in a dose-dependent manner (Fig. 7E).
