| Description | Biotin-PEG4-amide-Alkyne is a polyethylene glycol (PEG)-based linker, primarily used for synthesizing 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]. |
