Biotin-PEG3-bromide is a biotinylated PEG3 linker terminating in a reactive bromide. It provides a short, hydrophilic spacer for biotin conjugation and affinity capture, while the terminal bromide can be displaced by nucleophiles or used in cross-coupling reactions to install diverse handles. The reagent is intended for pull-down assays, streptavidin-mediated capture, and small-molecule bioconjugation workflows.
