ATTO 647N belongs to a new generation of fluorescent labels for the red spectral region. Characteristic features of the label are strong absorption, high fluorescence quantum yield, high thermal and photo-stability, and exceptionally high stability towards atmospheric ozone .

ATTO 647N is a cationic dye. After coupling to a substrate the dye carries a net electrical charge of +1. In common with most ATTO-labels, absorption and fluorescence are independent of pH in the range of 2 to 11, used in typical applications. As supplied ATTO 647N consists of a mixture of two isomers with practically identical absorption
