Amine-PEG4-Desthiobiotin is a PEG-based linker bearing a primary amine and a desthiobiotin moiety used to assemble proteolysis-targeting chimeras (PROTACs), affinity probes, and bioconjugates. The reagent supplies a hydrophilic spacer and a reactive handle to link target-binding ligands to recruiting ligands, supporting modular synthesis and downstream affinity-based workflows.

• Provides a primary amine for straightforward conjugation using standard amide-coupling chemistries.
• Contains a desthiobiotin moiety for reversible affinity capture with streptavidin-based systems.
• PEG4 spacer imparts hydrophilicity and flexible linkage between functional groups.
• High reported purity supports reproducible synthesis and analytical characterization.
• Stable when stored frozen and in solution under recommended conditions.
