ATTO 532 is a fluorescent label related to the well-known dye Rhodamine 6G. Characteristic features of the label are strong absorption, high fluorescence quantum yield, high photo-stability, and excellent water solubility. Thus ATTO 532 is highly suitable for single-molecule detection applications and high-resolution microscopy such as SIM, STED etc. Additionally the dye highly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH and many more.
The fluorescence is excited most efficiently in the range 515 - 545 nm. A suitable excitation source for ATTO 532 is the 532 nm output of the frequency-doubled Nd:YAG laser.
