Cat. No.: HY-D1055
CAS No.: 1003197-00-9
MitoSOX Red is a live cell fluorescent probe that specifically targets mitochondria and is cell membrane permeable. MitoSOX Red enters mitochondria and is oxidized by superoxide but not by other ROS or RNS generating systems. The oxidized MitoSOX Red then binds to nucleic acids in mitochondria/nucleus, producing strong red fluorescence. MitoSOX Red can be used as a fluorescent indicator to specifically detect superoxide. In addition, superoxide dismutase (SOD) can prevent the oxidation of MitoSOX Red.
Excitation/emission wavelength: 510/580 nm.

CAS No.: 104821-25-2
Synonyms: Hydroethidine; PD-MY 003
Dihydroethidium, also known as DHE, is a peroxide indicator. Dihydroethidium penetrates cell membranes to form a fluorescent protein complex with blue fluoresces. After entering the cells, Dihydroethidium is mainly localized in the cell membrane, cytoplasm and nucleus, and the staining effect is the strongest in the nucleus. Dihydroethidium produces inherent blue fluorescence with a maximum excitation wavelength of 370 nm and a maximum emission wavelength of 420 nm; after dehydrogenation, Dihydroethidium combines with RNA or DNA to produce red fluorescence with a maximum excitation wavelength of 300 nm and a maximum emission wavelength of 610 nm. 535 nm can also be used as the excitation wavelength for actual observation .
