Mal-PEG4-amine TFA salt

Biological Activity

Mal-PEG4-C2-NH2 TFA is a PEG-based PROTAC linker that 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].
