Product overview

Description & Application

Tri-GalNAc(OAc)3 Cbz is a ligand for asialoglycoprotein receptor (ASGPR) where the sugars are protected by acetylation and the tris tertiary amine is protected by benzyloxycarbonyloxy (Cbz). This peracetylated tri-GalNAc(OAc)3 Cbz can be serve as a valuable building block for ASGPR-targeted therapies. Its three branches or arms, each ending in a GalNAc sugar, ensure strong binding to hepatocyte ASGPR. However, the key feature lies in its protective groups: acetylated sugars allow for controlled removal to expose reactive sites for conjugation, while the Cbz-protected amine provides stability and can be selectively cleaved to introduce a reactive amine group for further biomolecule attachment, ultimately enabling researchers to tailor tri-GalNAc(OAc)3 Cbz into customized conjugates for specific therapeutic applications.

Handling guidance

Shipping, storage and sampling

How is the lipid shipped, and how should I store it?
Ships from Shanghai. Storage: 2 years -20°C Powder, 2 weeks 4°C in DMSO, 6 months -80°C in DMSO
Pure lipid or solution — which should I choose?
Pure lipid is generally more stable during shipping and storage, so we usually recommend the pure form. A solution in ethanol or chloroform can be supplied when required by your workflow. Tell us the intended application, solvent and target concentration so the most suitable format can be confirmed.
