ATTO 700 belongs together with ATTO 655 and ATTO 680 to a new generation of fluorescent labels.
Characteristic features of the label are strong absorption, high fluorescence quantum yield, good water solubility, and high thermal and photo-stability. ATTO 700 is a zwitterionic dye. After coupling to a substrate the dye moiety is electrically neutral.
ATTO 700 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 670 - 715 nm.
