Biotin-PEG4-azide features a cleavable PEG4 spacer linking biotin to a reactive azide group, enabling site-specific conjugation in bioorthogonal labeling. This derivative combines high-affinity biotin binding with efficient click chemistry compatibility, facilitating robust detection or immobilization under physiological conditions.
Biotin-PEG4-azide serves as a versatile bifunctional linker for bioconjugation, enabling site-specific labeling via strain-promoted or copper-catalyzed azide-alkyne cycloaddition. The PEG4 spacer provides enhanced solubility and reduced steric hindrance, while the azide group exhibits high reactivity and stability under physiological conditions. This reagent facilitates efficient conjugation to biomolecules and functional surfaces, making it ideal for affinity purification, immunoassays, and targeted delivery applications.
