Description

(+)-Biotin-PEG2-acid can modify surfaces of nanoparticles, microspheres, or other materials. The PEG spacer arm improves water solubility and reduces non-specific interactions, making it suitable for conjugation with biomolecules or ligands. Biotin is a water-soluble vitamin essential for various metabolic processes. It is commonly used as a molecular tag due to its high affinity for streptavidin and avidin proteins. The carboxylic acid group at the end of the PEG spacer arm provides a reactive site for conjugation reactions with primary amines or other functional groups.
