| Description | N-(m-PEG4)-N'-(m-PEG4)-O-(m-PEG4)-O'-(azide-PEG4)-Cy5 is a polyethylene glycol (PEG) derived linker compound employed in the synthesis of proteolysis targeting chimeras (PROTACs)[1]. |
| In vitro | PROTACs contain two different ligands connected by a linker; one is a ligand for an E3 ubiquitin ligase and the other is for the target protein. PROTACs exploit the intracellular ubiquitin-proteasome system to selectively degrade target proteins[1]. |
