DBCO-PEG12-maleimide is a bifunctional polyethylene glycol (PEG12) linker bearing a dibenzocyclooctyne (DBCO) group for strain-promoted alkyne-azide cycloaddition and a terminal maleimide for thiol-specific conjugation. It is designed for catalyst-free click chemistry and selective cysteine conjugation in bioconjugation workflows, linker synthesis, and chemical biology applications.

  • Enables copper-free click (SPAAC) reactions with azide-functionalized partners.
  • Reacts selectively with thiols via the maleimide to form stable thioether bonds.
  • PEG12 spacer improves solubility and provides flexible linker length.
  • High purity suitable for sensitive bioconjugation applications.
  • Stable when stored dry at recommended low temperatures.
