6-ROX is widely used in DNA sequencing and DNA probes based on fluorescent energy transfer (FRET). The succinimidyl ester reacts readily with primary or secondary amines under mild conditions. A stock solution of the dye can be made in anhydrous DMF or DMSO. The coupling reaction is usually carried out in a pH ~8.5 buffer (for example, 0.1-0.2 M sodium bicarbonate buffer). Alternatively, the coupling reaction may also be carried out in an organic solvent for amino compounds that are insoluble in aqueous solution.
