XFD568 amine

XFD568 amine is the same molecule to the Alexa Fluor(R) 568 amine (Alexa Fluor(R) is the trademark of ThermoFisher). It is a rhodamine dye with bright red-fluorescence optimal for labeling antibodies. XFD568 dye is water soluble and pH-insensitive from pH 4 to 10. The amine of XFD568 is a versatile carbonyl-reactive form for conjugating this fluorophore to peptides and other biological molecules. Solvent: DMSO. Correction Factor (260 nm): 0.45.
