产品详细信息

详细说明 (English)

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 520 shows a molar extinction of 110,000 and QY of 90% in water (95% in ethanol). Decay time is 3.6 ns.
Other Notes
Employed in confocal fluorescence microscopy to confirm formation of polymer nanoshells;1 using combined imaging and scanning fluorescence correlation spectroscopy to characterize microsecond emission fluctuation.2
