PE434015: Galα(1-3)LacNAc-PEG3-Azide label-new Fmoc-Ser(β-D-Mel(Ac)7)-OHC26H46N4O18 702. 66 A Gal1 3LacNAc ( Gal epitope) ligand equipped with an azide handle through a hydrophilic PEG3 spacer. The terminal azide couples to alkynes via copper catalyzed azide alkyne cycloaddition (CuAAC) or to DBCO and related strained alkynes via copper free click chemistry, forming stable 1,2,3 triazole linkages. This compound presents a terminal Gal1 3 linkage corresponding to the Gal epitope (Gal1 3Gal1 4GlcNAc Gal1 3lactose), the
