ATTO 655 belongs together with ATTO 680 und ATTO 700 to a new generation of fluorescent labels. Characteristic features of the label are strong absorption, high fluorescence quantum yield, high thermal and photo-stability, exceptionally high stability towards atmospheric ozone , and very good water solubility. Thus ATTO 655 is highly suitable for single-molecule detection applications and high-resolution microscopy such as PALM, dSTORM, STED etc. Additionally the dye highly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH) and many more. ATTO 655 is a zwitterionic dye. After coupling to a substrate the dye moiety is electrically neutral. ATTO 655 is a strong electron acceptor. Its fluorescence is efficiently quenched by electron donors like guanine, tryptophan, etc. The fluorescence is excited most efficiently in the range 640 - 660 nm. A suitable excitation source is the 647 nm line of the Krypton-Ion laser or a diode-laser emitting at 650 nm.
