Trivalent GalNAc-DBCO is a synthetic trivalent N-acetylgalactosamine (GalNAc) ligand functionalized with a dibenzocyclooctyne (DBCO) moiety. It is intended for strain-promoted alkyne-azide cycloaddition (SPAAC) to enable copper-free click conjugation to azide-modified oligonucleotides and other biomolecules, and can direct conjugated cargo to the asialoglycoprotein receptor (ASGPR) for hepatocyte targeting and lysosomal trafficking.
- Enables copper-free click conjugation via strain-promoted alkyne-azide cycloaddition.
- Designed for conjugation to azide-modified oligonucleotides and biomolecules.
- Triantennary GalNAc motif targets ASGPR for liver-directed delivery.
- High purity suitable for biochemical and conjugation workflows.
- Available in small-scale 10 mg packs for research use.
