PE035010: Neu5Acα(2-6)LacNAc-PEG3-Azide Pack Size:1 mg / Fmoc-Tyr(Gal(Ac)4-β-D)-OH / Fmoc-L-Tyr(Gal(Ac)4-β-D)-OHC31H53N5O21 831. 77 A Neu5Ac2 6LacNAc (Neu5Ac2 6Gal1 4GlcNAc) trisaccharide equipped with an azide functionalized linker through a hydrophilic triethylene glycol (PEG3) spacer. The terminal azide can be covalently coupled to alkyne partners via copper catalyzed azide alkyne cycloaddition (CuAAC), or to dibenzocyclooctyne (DBCO) and related strained alkynes using copper free click chemistry, forming stable 1,2,3 triazole linkages. Neu5Ac2 6LacNAc is a
