Optical properties
ATTO Rho11 is a new rhodamine dye featuring a functionality for coupling to biomolecules such as DNA, RNA, proteins etc. The label shows very high fluorescence efficiency and exceptionally high photo-stability.
The dye is moderately hydrophilic. ATTO Rho11 is a cationic dye. After coupling to a substrate the label carries a net electrical charge of +1. In solution its fluorescence can be excited efficiently in the range 550 - 580 nm.
