Hydroxy-PEG4-CH2-Boc

Hydroxy-PEG4-CH2-Boc is a Boc-protected, heterobifunctional PEG linker used in constructing PROTAC molecules for targeted protein degradation. It connects an E3 ligase ligand to a protein-of-interest ligand, enabling the study of ubiquitin-proteasome system function in both cellular and in vivo research models.
