ATTO 542 is a new fluorescent label related to ATTO 532. The new dye is very hydrophilic and shows excellent water solubility. Characteristic features of the label are strong absorption and high photo-stability. The dye shows a very high fluorescence quantum yield even after coupling to a biomolecule. ATTO 542 is very suitable for oligonucleotide labeling, single-molecule detection applications and high-resolution microscopy (PALM, dSTORM, STED etc.). Additionally the dye strongly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH) and many more.
After coupling to a substrate the dye carries a net electrical charge of - 3. The fluorescence is excited most efficiently in the range 520 - 555 nm.
