Dioxoisoindolin-O-PEG-OH (MW 2000) is a polyethylene glycol (PEG)-based linker utilized for the synthesis of PROTACs (proteolysis targeting chimeras)[1].
m-PEG-OH (MW 2000) is a PEG-based linker for PROTACs which joins two essential ligands, crucial for forming PROTAC molecules. This linker enables selective protein degradation by leveraging the ubiquitin-proteasome system within cells.
