MV100040: Tris-GalNAc-β-Ala-PEG4-DBCO label-new Sialyl Tn or sTn (Neu5Acα2-6GalNAcα-O-Ser)C94H149N13O35 2021. 25 A triantennary N acetylgalactosamine (Tri GalNAc) ligand presenting three GalNAc residues on a tris based branched scaffold, extended through a alanine linker and a discrete tetraethylene glycol (PEG4) spacer to a terminal dibenzocyclooctyne (DBCO) handle. The DBCO group reacts with azide functionalized partners via copper free strain promoted azide alkyne cycloaddition (SPAAC), forming stable 1,2,3 triazole linkages without a
