Atto Rho14 NHS ester is a new rhodamine featuring a functionality for coupling to bio-molecules such as DNA, RNA or proteins. The label shows strong absorption and extraordinarily high fluorescence quantum yield. ATTO Rho14 is the brightest label available in this wavelength range. The dye exhibits an exceptionally high photostability. In common with most ATTO-labels, absorption and fluorescence are pH-independent in the range of pH 2 to 11, used in typical applications. The dye is moderately hydrophilic. After coupling to a substrate ATTO Rho14 carries a net electrical charge of +1.

Probes to dye for: Rhodamine-inspired Si-pyronine, Si-rhodamine, Te-rhodamine, and Changsha NIR dyes have been developed recently. These dyes show fluorescence in the far-red to near-infrared region, while retaining the advantages of the original rhodamines, such as high fluorescence quantum yield...
