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 NHS-ester of the dye reacts easily with amino-groups of proteins and other bio-molecules. Since the amino group must be non protonated to be reactive, the pH of the reaction is recommended to be about 8.3. Prepare labeling solution of NHS-ester immediately before use by dissolving the vial content in anhydrous and amine-free DMF or DMSO.
