Features and Benefits: dPEG48 biotin acid is a 2,500 Dalton biotin acid product that contains a 157 atom (187.8 Å) dPEG spacer. Amphiphilic dPEG48 biotin acid dissolves in water or aqueous buffer and organic solvents. It does not cause aggregation or precipitation of biomolecules. Using 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC) chemistry, dPEG48 biotin acid couples to free primary amines in aqueous media. These free amines can be on a protein, peptide, or the treated surface of a nanoparticle. Moreover, the terminal propionic acid moiety can be functionalized with other reactive groups for coupling directly to surfaces such as glass, gold, or magnetic nanoparticles. dPEG48 biotin acid is a monodisperse equivalent of the polymeric PEG2000.
