General description
Atto 550 is a new label with high molecular absorption (120,000) and quantum yield (0.80) as well as sufficient Stokes shift between excitation and emission maximum. Atto 550 can be used with similar excitation source and fluorescence filters as Cy3™ and is characterized by a high photostability.

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 550, which is similar to Cy3™, may be useful in applications such as fluorescence resonance energy transfer (FRET) and as a tag for molecules such as secondary antibodies.
