Octaethyleneglycol 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.
C12E8 is a nonionic surfactant formed by the ethoxylation of dodecanol, yielding a compound with eight repeated units of ethylene glycol. It can be used for solubilization of membrane-bound proteins.
