| Dihydroethidium (also called hydroethidium) is the chemically reduced form of the commonly used DNA dye ethidium bromide. The probe is useful to detect oxidative activities in viable cells, including respiratory burst in phagocytes. Dihydroethidium itself has blue fluorescence (lambda Ex/lambda Em: 355/420nm) in cells, while the oxidized form ethidium has red fluorescence (lambda Ex/lambda Em: 518/605 nm) upon DNA intercalation.Off-white to light brown solid soluble in DMF or DMSOStore at -20C under nitrogen or argon, and protect from light, especially when in solutionC21H21N3MW: 315[38483-26-0] |
