Product Description: AF 430 alkyne is a derivative of the yellow fluorescent dye AF 430. AF430 has an excitation wavelength of 430 nm and an emission wavelength of 542 nm. AF 430 alkyne can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) via Alkyne groups and molecules containing Azide groups. To achieve specific coupling of dye labels and biomolecules.
