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 488 is suitable for preparation of fluorescence labeling reagents and the study of its physicochemical properties. |
General description: | Atto 488 is a labeling dye with high molecular absorption (90,000) and quantum yield (0.80) as well as sufficient Stokes shift between excitation and emission maximum. It is optimized for excitation with an argon laser, and is characterized by high photostability. |
