Biotin-PEG4-picolyl azide is a biotinylated click-chemistry reagent containing a PEG4 spacer and a picolyl azide moiety. It is designed for copper-catalyzed azide-alkyne cycloaddition (CuAAC) to conjugate biotin to alkyne-containing biomolecules for labeling, enrichment, and detection in chemical biology workflows.

  • Picolyl azide enhances copper-catalyzed azide-alkyne cycloaddition kinetics.
  • PEG4 spacer improves solubility and provides a flexible linkage.
  • Biotin tag enables affinity capture and detection of conjugates.
  • High purity suitable for analytical and preparative labeling workflows.
  • Small pack size appropriate for milligram-scale reactions.
