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.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
