Mal-PEG4- (PEG3-DBCO) - (PEG3-TCO)

This heterobifunctional linker is a 10-unit polyethylene glycol (PEG) spacer designed for constructing antibody-drug conjugates (ADCs) . It features a maleimide group for thiol conjugation and a TCO group for rapid, bioorthogonal iEDDA click chemistry with tetrazines, enabling precise assembly of ADCs for both in vitro and in vivo therapeutic research.
