TCI Biotin-PEG11-Amine (CAS 1418022-42-0) is a bioconjugation reagent featuring a biotin moiety linked to a reactive primary amine group via an 11-unit PEG spacer, designed for efficient and flexible biotinylation of biomolecules. The amine group enables covalent coupling to carboxyl groups, activated esters, or other electrophilic functional groups on proteins, antibodies, peptides, and nucleic acids, while the PEG11 spacer enhances water solubility and reduces non-specific binding. This product is widely applied in biochemical assays, affinity purification, surface functionalization, and the development of targeted delivery systems across life science and chemical biology research.
