Biotin-PEG6-Mal is a biotin-labeled polyethylene glycol (PEG6) maleimide linker that enables thiol-selective conjugation to introduce a biotin affinity tag for capture or detection using streptavidin/avidin systems. It is commonly used in PROTAC assembly and bioconjugation workflows where solubility and specific thiol reactivity are required.

  • Thiol-selective maleimide group for rapid, specific conjugation.
  • PEG6 spacer improves solubility and reduces steric hindrance.
  • Biotin affinity tag enables high-affinity streptavidin/avidin capture.
  • High purity supports reproducible experimental results.
  • Stable as a powdered reagent with defined cold-storage recommendations.
