  • Tri-β-GalNAc-PEG3-Azide enables the possibility to click label an Alkyne or DBCO modified target with an Tri-GalNAc moiety by copper-catalyzed Azide-Alkyne Chemistry (CuAAC). The Tri-GalNAc structure is recognized by the desialic acid glycoprotein receptor (ASGPR) and can be therefore used to target delivery of biomolecules as siRNA to liver tissue.
