XFD647 NHS Ester *Same Structure to Alexa Fluor™ 647 NHS Ester*
XFD647 is manufactured by AAT Bioquest, and it has the same chemical structure of Alexa Fluor® 647 (Alexa Fluor® is the trademark of ThermoFisher). It is a bright red fluorescent dye. XFD647 dye is water soluble and pH-insensitive from pH 4 to pH 10. The NHS ester (or succinimidyl ester) of XFD647 is the most convenient amine-reactive form for conjugating this dye to a protein or antibody.
