PE131020: β-GalNAc-PEG3-DBCO Pack Size:2.5 mg β-D-(Galβ1-4Glc)-O-(CH2)2-NH2C33H41N3O10 639. 69 A D N acetylgalactosamine (GalNAc) ligand equipped with a dibenzocyclooctyne (DBCO) handle through a hydrophilic PEG3 spacer. The DBCO group reacts with azides via copper free strain promoted azide alkyne cycloaddition (SPAAC), forming stable 1,2,3 triazole linkages without a copper catalyst. This compound enables the construction of hepatocyte targeted therapeutics and research tools that exploit the asialoglycoprotein receptor
