Description

5-ROX (5-Carboxy-X-Rhodamine, Triethylammonium Salt), single isomer

The carboxylic acid of 5-ROX is used for oligonucleotide labeling and automated DNA sequencing 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.

Frequently Asked Questions (FAQs)

What is the excitation and emission wavelength for rhodamine?

Rhodamine is a generic term for a wide variety of cationic dyes whose fluorescence emission can range from green, orange to red. The table below lists the excitation and emission maxima (nm), as well as molar extinction coefficients (“EC”; cm-1 M-1), for various rhodamine dyes (data derived with dye dissolved in methanol).
