General description

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