DBCO-PEG4-desthiobiotin is a heterobifunctional PEG-based linker that combines a dibenzocyclooctyne (DBCO) group for strain-promoted azide-alkyne cycloaddition (SPAAC) with a desthiobiotin moiety for reversible streptavidin affinity. The short PEG4 spacer improves solubility and reduces steric hindrance, making the reagent suitable for bioconjugation, labeling, and linker synthesis applications.

  • Enables copper-free click chemistry via strain-promoted azide-alkyne cycloaddition.
  • Provides reversible affinity capture through desthiobiotin-streptavidin interaction.
  • PEG4 spacer improves aqueous solubility and reduces steric hindrance.
  • Suitable for bioconjugation, labeling, and linker synthesis applications.
  • High reported purity (96.4%) and small-scale pack sizes for research use.
  • Supplied as a light yellow to yellow oil; soluble in organic solvents and DMSO.
