DRAQ7™ is a cell-impermeable, far-red fluorescing DNA dye that is commonly used to assess cell viability. As it is cell-impermeable, it only stains DNA in dead or permeabilized cells. Far-red emitting dyes, like DRAQ7™, are compatible with commonly used reporter proteins and fluorescent tags. DRAQ7™ shows negligible cytotoxicity and low photobleaching, so it is amenable with real-time and kinetic cell viability assays. Excitation and emission maxima are 599/644 and 697 nm, respectively.
