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. And 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 brightness of signals and leads to environment dependency, e.g., spectral shifts by conjugation.
Atto 610 shows an molar extinction of 110,000 and QY of 70% in water (70% in ethanol). Decay time is 3.3 ns.
