DBCO-PEG4-maleimide is a bifunctional PEG4 linker bearing a strained dibenzocyclooctyne (DBCO) and a terminal maleimide. It enables site-selective conjugation by combining thiol-maleimide chemistry with strain-promoted azide-alkyne cycloaddition, making it suitable for antibody-drug conjugate assembly and other bioconjugation workflows.

  • Enables site-selective conjugation via thiol-maleimide coupling and SPAAC
  • Contains a PEG4 spacer for increased solubility and reduced steric hindrance
  • Liquid form, colorless to light yellow, suitable for solution-phase reactions
  • High reported purity supports reproducible conjugation results
  • Soluble in DMSO at approximately 50 mg/mL; ultrasonic assistance may be required
  • Store protected from light; keep frozen under inert atmosphere for long-term storage
