XFD555 acid is the same molecule to the Alexa Fluor® 555 acid (Alexa Fluor® is the trademark of ThermoFisher). It is a cyanine dye with bright yellow-fluorescent dye optimal for labeling antibodies. XFD555 dye is water soluble and pH-insensitive from pH 4 to 10. XFD555 acid is the most economic amine-reactive form for conjugating this dye to a peptide.
