Biotin-PEG4-Amide-C6-Azide（Cat No.:I015737）is a bifunctional bioconjugation reagent that combines biotin for strong streptavidin/avidin binding with a terminal azide group for click chemistry with alkynes. The PEG4 spacer enhances solubility, flexibility, and minimizes steric hindrance, while the C6 amide linker provides additional length and stability, ensuring efficient biomolecular interactions. This design allows for site-specific labeling, enrichment, and capture of biomolecules in complex systems. Widely applied in proteomics, chemical biology, imaging, and drug discovery, Biotin-PEG4-Amide-C6-Azide offers reliable performance in affinity purification and controlled bioconjugation strategies.
