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.
General description
Atto 635 is a new label with high molecular absorption (120,000) and quantum yield (0.25) as well as sufficient Stokes shift between excitation and emission maximum. This label is optimized for use with diode laser excitation at 635 nm and is characterized by high photostability.
