ATTO Oxa12 is a lipophilic variety of ATTO 655.
Characteristic features of the label are strong absorption, good fluorescence quantum yield, excellent thermal and photo-stability, and outstanding ozone resistance. Absorption and fluorescence are pH-independent in the range pH 2 to 11, used in typical applications.
ATTO Oxa12 shows excellent solubility in polar organic solvents like DMF, DMSO or acetonitrile. ATTO Oxa12 is a cationic dye. After coupling to a substrate the dye carries a net electrical charge of +1. The fluorescence is excited most efficiently in the range 640 - 675 nm. A suitable excitation source is the 647 nm line of the Krypton-Ion laser or a diode-laser emitting at 650 nm.
