DRAQ7 DROP & GO Dye is a bright, easy-to-use fluorescent DNA dye used to exclude non-viable cells by flow cytometry. This dye has excitation maxima at 599/644 nm and emission maxima at 678/697 nm.
• Stable at room temperature
• Convenient, ready-to-use dropper-bottle format—no need to dilute, weigh, or pipette
• No UV excitation and no emission spectral overlap with PE
DRAQ7 Dye is a membrane-impermeable dye that rapidly stains the double-stranded DNA (dsDNA) of dead or permeabilized cells. The dye can be excited by wavelengths from 488 to 647 nm, though it is optimally excited by red laser lines. Its emission maxima is at 697 nm when intercalated with dsDNA.
