Biotin-C5-Azide (Cat No.: I042596) is a biotinylated probe featuring a five-carbon (C5) linker and an azide functional group, enabling efficient bioorthogonal conjugation via click chemistry. The extended spacer enhances accessibility for streptavidin-based detection or purification while minimizing steric hindrance. Biotin-C5-Azide is ideal for labeling azide-reactive biomolecules in proteomics, cell surface tagging, and imaging studies. Its water solubility and high reactivity make it a versatile tool for targeted enrichment, biomolecule tracking, and applications in chemical biology and molecular diagnostics.
