In the intricate world of biomolecular science and biotechnology, precise and efficient conjugation of molecules is a cornerstone of innovation. Biotin-PEG3-Azide (CAS 875770-34-6) has established itself as a premier reagent for such applications, combining the high-affinity binding of biotin with the versatile reactivity of an azide group, all connected by a beneficial PEG linker. As a reputable manufacturer and supplier, we provide this essential compound to empower researchers and developers globally.

The primary strength of Biotin-PEG3-Azide lies in its dual functionality and the advantageous properties conferred by the PEG3 linker. The biotin moiety offers unparalleled specificity for avidin and streptavidin, facilitating easy detection, capture, and purification of conjugated biomolecules. The PEG3 linker, being hydrophilic and flexible, enhances the solubility of the conjugate, minimizes steric hindrance, and can improve the overall stability and performance of the biomolecule in biological systems. The terminal azide group is the key to its integration into modern bioconjugation strategies, most notably click chemistry.

Click chemistry, particularly the copper-catalyzed or copper-free azide-alkyne cycloaddition, provides a highly efficient and bioorthogonal method for creating stable covalent bonds. Biotin-PEG3-Azide is perfectly designed to participate in these reactions, allowing for the precise labeling of alkyne-functionalized proteins, peptides, oligonucleotides, and even nanoparticles. This precise labeling is critical for a wide array of applications, including the development of diagnostic assays, targeted therapeutic agents, and advanced functionalized materials.
