The carboxylic acid of 5-ROX is used for oligonucleotide labeling and automated DNA sequencing applications. Often a dye of choice for fluorescence resonance energy transfer (FRET) and fluorescence quenching applications. Conjugates of this dye have longer-wavelength spectra than the spectra of Lisaamine™ rhodamine B conjugates, but somewhat shorter-wavelength spectra than those of Texas Red™ conjugates.
