XFD568 is manufactured by AAT Bioquest, and it has the same chemical structure of Alexa Fluor® 568 (Alexa Fluor® is the trademark of ThermoFisher). It is a bright red-fluorescent dye optimal for use with the 568 nm laser line. XFD568 dye is water soluble and pH-insensitive from pH 4 to pH 10. XFD568 acid is the most economic amine-reactive form for conjugating Alexa Fluor® 568 fluorophore to a peptide.
