DETAILS

Description (简体中文)

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.
Other Notes
New red absorbing fluorescent dye as a biophysical probe for binding interactions;1,2 used as fluorescence tracer in spray diagnostics.3
