PE434005: β-Gal-PEG3-Azide (Peracetate) label-new Sialyl Tn or STn (Neu5Acα2-6GalNAcα-O-Thr)C20H31N3O12 505. 47 A peracetylated D galactose 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. The sugar hydroxyls are acetate protected to increase lipophilicity for cell membrane permeability. This compound provides a
