PE934010: β-LacNAc-PEG3-Azide label-new Sialyl Tn or STn (Neu5Acα2-6GalNAcα-O-Ser)C20H36N4O13 540. 52 A D N acetyllactosamine (LacNAc) 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 provides an N acetyllactosamine (LacNAc; Gal1 4GlcNAc) building block, a core disaccharide of N and O glycans
