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 647 is a zwitterionic dye with a net electrical charge of zero. It is a pH sensitive product. While practically stable up to pH 8.5, it slowly degrades at higher pH. Atto 647 is a new label with high molecular absorption (120,000) and quantum yield (0.20) as well as enough Stokes shift between excitation and emission maximum. Atto 647 is characterized by a high photostability and brightness. In addition, this label has good water solubility and low triplet formation ability.
