XFD488 NHS Ester (Succinimidyl Ester) is the same molecule to the Alexa Fluor® 488 NHS Ester (Alexa Fluor® is the trademark of ThermoFisher). It is a bright green-fluorescent dye optimal for use with the 488 nm Argon laser. XFD488 dye is water soluble and pH-insensitive from pH 4 to pH 10. The NHS ester (or succinimidyl ester) of XFD488 is the most convenient amine-reactive form for conjugating this dye to a protein or antibody.
