PEG20-Tos

PROTAC Linkers

PEG20-Tos is a polyethylene glycol (PEG)-based linker designed for use in the synthesis of proteolysis-targeting chimeras (PROTACs). By providing a flexible and soluble connection between the E3 ligase recruiter and the target protein, PEG20-Tos enhances the efficiency of targeted protein degradation. This reagent is essential for studies involving targeted protein modulation and therapeutic development in cancer and other diseases.
