General description
Atto 465 is a new label with strong absorption and fluorescence and a large stoke′s shift (excitation maximum 453 nm, emission maximum 508 nm). The dye is characterized by high photostability and thermal stability. The dye is moderately hydrophilic, the NHS-ester and maleimide derivatives are very well soluble in polar solvents as DMSO, DMF or acetonitrile. At low temperatures or embedded into polymeric matrices it shows intense phosphorescence.
Application
Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation. Atto 465 is suitable for preparation of fluorescence labeling reagents and studies of the physicochemical properties of the dye.
