Atto 495 

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 495 is a new label for proteins and oligo-nucleotides with high molecular absorption (80.000) and quantum yield (0.45) as well as sufficient Stoke's shift between excitation and emission maximum. Atto 495 is characterized by a high photostability and thermostability. It is slightly hydrophilic, and solubility in polar solvents as DMF or DMSO is high.
