The isomeric 6-ROX, SE is an amine-reactive form of carboxy-X-rhodamine and is widely used for oligonucleotide labeling and automated DNA sequencing applications.
ROX dyes have a strong red fluorescence.Their excitation and emission wavelengths are longer than those of traditional rhodamine dyes.They are used as labels for peptides, proteins, and other biological ligands.5-ROX, 6-ROx, and their mixture of 5(6) -RoX
