ATTO 390 is a novel fluorescent label with a coumarin structure. Characteristic features of the label are high fluorescence quantum yield, large Stokes-shift, good photo-stability, and low molecular weight. ATTO 390 is moderately hydrophilic. Its fluorescence can be excited efficiently in the range 360 - 410 nm. A useful excitation source is, e.g., a Mercury Arc Lamp with its lines at 365 nm and 405 nm.
