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.
