Biological Activity for tri-GalNAc-PEG3-Azide

tri-GalNAc-PEG3-Azide is a functionalized asialoglycoprotein receptor (ASGPR) ligand for lysosomal targeting chimera (LYTAC) research and development; each molecule incorporates three ASGPR ligands with a PEG3 linker and azide group reactive handle ready for conjugation. Upon binding to the ASGPR, tri-GalNAc conjugates are efficiently internalized via ASGPR-mediated endocytosis. tri-GalNAc conjugation can be employed as a strategy to effectively deliver cargo such as RNA or Cas9 complexes in a cell-specific manner to hepatocytes. Can be used to generate LYTACs, or labeled with dye for tissue imaging.

Targeted Protein Degradation Poster

Degraders (e.g. PROTACs) are bifunctional small molecules, that harness the Ubiquitin Proteasome System (UPS) to selectively degrade target proteins within cells. They consist of three covalently linked components: an E3 ubiquitin ligase ligand, a linker and a ligand for the target protein of interest. Authored in-house, this poster outlines the generation of a toolbox of building blocks for the development of Degraders. The characteristics and selection of each of these components are discussed.
