| Description | Biotin-PEG4-hydrazide, a biotin-labeled polyethylene glycol (PEG)-based hydrazide compound, is used as a linker in the synthesis of proteolysis targeting chimeras (PROTACs)[1]. |
| In vitro | PROTACs comprise two distinct ligands linked together: one targets an E3 ubiquitin ligase, and the other binds to the target protein. By leveraging the intracellular ubiquitin-proteasome system, PROTACs selectively degrade target proteins [1]. |
