PE934030: Galβ(1-3)GalNAc-α-PEG3-Azide label-new Tri-GalNAc-β-Ala-PEG3-BiotinC20H36N4O13 540. 52 A core 1 T antigen (Gal1 3GalNAc) 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 the core 1 T antigen (Gal1 3GalNAc), a tumor associated carbohydrate antigen and ligand for
