Dihydroethidium ≥98%
Dihydroethidium is a cell-permeable blue fluorescent dye that upon entering cells interacts with superoxide to form oxyethidium, which intercalates with nucleic acids and emits a red fluorescence detectable qualitatively by fluorescent microscopy or quantitatively by HPLC.
It displays excitation/emission spectra of 490/590 nm. This selective and sensitive probe can be used to detect reactive oxygen species during the phagocytic respiratory burst and for the detection of intracellular superoxide in cultured cells.
