GalNAc-L96-Succinate is a conjugate support-loading precursor for oligonucleotide synthesis: the free-acid form of a triantennary (trivalent) N-acetylgalactosamine ("GalNAc", L96) cluster joined to a succinate half-ester. Key identifiers include CAS 1159408-61-3, molecular formula C121H179N11O45, and molecular weight 2507.8 (PubChem CID 162394059). The triethylammonium salt of the same cluster is catalogued as CH67002.
Unlike a phosphoramidite, this reagent carries a 3'-O-succinate half-ester rather than a coupling group. The succinate is the conventional linker for attaching a 3'-terminal unit — here the GalNAc cluster — to an amino-functionalized solid support, so the oligonucleotide is then assembled carrying the GalNAc ligand at its 3'-end. The succinyl linkage is base-cleavable and is broken during deprotection to release the finished conjugate. Triantennary GalNAc binds the asialoglycoprotein receptor (ASGPR), a lectin on the surface of hepatocytes.

자주 묻는 질문
How does this differ from GalNAc-L96-Succinate, TEA salt (CH67002)?
This is the free-acid form of the same triantennary GalNAc cluster succinate; CH67002 is the triethylammonium (TEA) salt. Both serve the same role as a 3'-GalNAc support-loading precursor.
What is a triantennary GalNAc cluster, and what does it bind?
It is a trivalent presentation of N-acetylgalactosamine (three GalNAc sugars on a branched scaffold). Triantennary GalNAc binds the asialoglycoprotein receptor (ASGPR), a lectin on the surface of hepatocytes.
