This ATTO 488 is the free carboxy form and may be used for any kind of spectroscopy. Stock solutions can be prepared with water or aqueous buffer. Due to the high extinction coefficient and its high quantum yield of fluorescence this product is suitable for high-sensitivity detection including single-molecule work. The dye can be activated at the carboxy group for coupling to bio-molecules. For this purpose, dry and amine free DMF or DMSO must be used to dissolve the dye.

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.
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.
