Biological Activity for SJF 1521

SJF 1521 is a selective EGFR PROTAC® Degrader. SJF 1521 comprises the EGFR inhibitor lapatinib (Cat. No. 6811) joined by a linker to a von Hippel-Lindau (VHL) recruiting ligand. Exhibits selectivity for EGFR, including mutant forms, over HER2. Induces degradation of EGFR in OVCAR8 cells.

EGFR antibody validated for Simple Western™ (automated Western) instruments and Western Blot also available: Catalog # AF231

Targeted Protein Degradation Poster

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.
