General description
Atto 665 is a new fluorescent label closely related to Atto 647N. It shows extraordinary high fluorescence quantum yield, excellent thermal and photo-stability, outstanding ozone resistance, and very little triplet formation. Atto 665 is a cationic (charge +1). The dye is moderately hydrophilic. The maleimide of the dye is suitable for labeling sulfhydryl (thiol) groups of proteins, in particular. Cystein residues. Prepare labeling solution of maleimide-derivative immediately before use by dissolving the vial content in anhydrous and amine-free DMF or DMSO.
