MV100030: Tris-β-GalNAc-β-Ala-PEG3-N3 label-new 6-di-O-acetyl-2-deoxy-α-D-galactopyranosyl}-N α-(fluoren-9-yl-methoxycarbonyl)-L-ThreonineC73H130N14O32 1715. 9 A triantennary N acetylgalactosamine (Tri GalNAc) ligand presenting three GalNAc residues on a tris based branched scaffold, extended through a alanine linker and a hydrophilic, discrete triethylene glycol (PEG3) spacer to a terminal azide handle. The azide can be covalently coupled to alkyne partners via copper catalyzed azide alkyne cycloaddition (CuAAC), or to dibenzocyclooctyne (DBCO) and related strained alkynes via copper
