Optical properties
ATTO 488 is a hydrophilic fluorescent label with excellent water solubility. The dye exhibits strong absorption, high fluorescence quantum yield, and exceptional thermal and photo-stability. Thus ATTO 488 is highly suitable for single-molecule detection applications and high-resolution microscopy such as PALM, dSTORM, STED etc. Additionally the dye highly qualifies to be applied in flow cytometry (FACS), fluorescence in-situ hybridization (FISH and many more. The fluorescence is excited most efficiently in the range 480 - 515 nm.
A suitable source of excitation is the 488 nm line of an Argon-Ion laser.
