General description

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 680 shows a molar extinction of 120,000 and QY of 30% in water (40% in ethanol). Decay time is 1.8 ns.

Atto 680 has been used as a dye to study the fluorescence quantum yields of bioanalytically relevant red dyes.
