Boc-NH-PEG2-C2-amido-C4-acid (PROTAC Linker 30) is a PEG-based PROTAC linker can be used in the synthesis of PROTACs[1]. 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].
