XFD750 acid

XFD750 acid is the same molecule to the Alexa Fluor® 750 acid (Alexa Fluor® is the trademark of ThermoFisher). It is a cyanine dye with bright NIR-fluorescence optimal for labeling antibodies. It has the identical spectra to Cy7 dye. XFD750 dye is water soluble and pH-insensitive from pH 4 to 10. XFD750 acid is the most economic amine-reactive form for conjugating this dye to a peptide.
