AF 568 alkyne

AF 568 alkyne is a derivative of the orange fluorescent dye AF 568. AF 568 has an absorption wavelength of 590-720 nm (FRET) and an emission wavelength of 515-720 nm. AF 568 alkyne can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) via the Alkyne group and molecules containing Azide groups. To achieve specific coupling of dye labels and biomolecules[1].
