Biotin-PEG3-bromide is a biotinylated short polyethylene glycol (PEG3) linker terminated with an alkyl bromide. The bromide serves as a reactive leaving group for nucleophilic substitution or cross-coupling reactions, while the biotin enables affinity capture via streptavidin. The PEG3 spacer improves solubility and reduces steric hindrance in bioconjugation and pull-down assays.

  • Reactive alkyl bromide for nucleophilic substitution and cross-coupling
  • Biotin moiety enables affinity capture with streptavidin
  • PEG3 spacer enhances solubility and reduces steric hindrance
  • High purity (95.0%) suitable for analytical and preparative use
  • Available in small quantities for research use (50 MG)
