Description

Rhodamine Red™-X, Succinimidyl Ester, 5-isomer

The amine-reactive Rhodamine Red™-X, succinimidyl ester can be used to create red-fluorescent bioconjugates with excitation/emission maxima ∼560/580 nm. This reactive dye contains an additional seven-atom aminohexanoyl spacer ('X') between the fluorophore and the succinimidyl ester group. This spacer helps to separate the fluorophore from its point of attachment, potentially reducing the interaction of the fluorophore with the biomolecule to which it is conjugated.

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).
