General description
CF™620R dye is a far-red rhodamine-based fluorescent dye. The dye is highly fluorescent and extremely photostable. With its absorption and emission maxima centered at 617 and 639 nm, respectively, the dye may be used as an excellent energy acceptor in fluorescence resonance energy transfer (FRET), or used in multi-color detection applications where the excitation and emission windows can be matched with the spectral profiles of the dye for maximal fluorescence collection. The exceptional water solubility of the dye facilitates bioconjugation in aqueous media and better retains the biological specificity of the conjugates.
Features and Benefits
1. Highly water-soluble. 2. Highly fluorescent. 3. Extremely photostable.
Preparation Note
Dissolve in DMSO
Protect from light and moisture
