产品详细信息

详细说明 (English)

Application
Atto labels are designed for highest sensitivity applications. A unique combination of advantages makes them highly favorable tools for all kinds of labeling applications. Some of their properties make them specifically interesting for single molecule detection. Atto labels are based on rigid structures and do not show any cis-trans-isomerization, which lowers the brightness of signals and leads to environment dependency, e.g., spectral shifts by conjugation. Atto 655 shows a molar extinction of 110,000 and QY of 30% in water (50% in ethanol). Decay time is 1.9 ns.
Other Notes
New red absorbing fluorescent dye with best signal-to-noise ratio and long fluorescence life-time. Useful as a biophysical probe for binding interactions.1
