Biotin-PEG8-azide is a biotinylated polyethylene glycol (PEG) linker bearing an azide functional group for click chemistry. The PEG8 spacer improves solubility and reduces steric hindrance; the azide enables covalent coupling to alkyne-containing molecules via azide-alkyne cycloaddition, and the biotin moiety allows high-affinity capture and detection with streptavidin/avidin systems. Intended for research use in bioconjugation and surface modification applications.
- Enables Cu(I)-catalyzed or strain-promoted azide-alkyne cycloaddition.
- Provides biotin tag for streptavidin/avidin capture and detection.
- PEG8 spacer increases solubility and reduces steric interference.
- High purity suitable for research bioconjugation workflows.
- Stable as a powder at -20°C for long-term storage.
