ATTO 565 is a novel fluorescent label belonging to the class of rhodamine dyes. Characteristic features of the label are strong absorption, high fluorescence quantum yield, and high thermal and photo-stability. 

Thus ATTO 565 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.
The dye is moderately hydrophilic. The fluorescence is excited most efficiently in the range 545 - 575 nm. As supplied ATTO 565 consists of a mixture of two isomers with practically identical absorption and fluorescence. However, on request the dye can also be supplied as single isomer.
