Amino-dPEG®8-acid, product number QBD-10277, is an amino PEG acid. A primary amine and propionic acid terminate the ends of the polyethylene glycol (PEG) spacer. The single molecular weight PEG spacer is discrete (Ð = 1) and highly hydrophilic. Consequently, it increases the hydrodynamic volume and imparts water solubility to conjugates that incorporate it.
Both ends of the molecule are available for conjugation. Conjugation of only one end of the dPEG® spacer may modify the overall charge of the conjugate. Many different types of coupling reactions are effective for this purpose. However, care should be taken not to use single-step EDC coupling, as this will polymerize the dPEG® product.
Scientific publications report the use of Amino-dPEG®8-acid in modifying diverse compounds including antibodies, enzymes, carbon nanotubes, and SU-8 (an epoxy-based negative photoresist) layered atop a quartz surface. In each case, amino-dPEG®8-acid was shown to improve the performance of the conjugate compared to the unmodified material. The improved conjugate performance occurred through increased signal-to-noise ratio, reduced non-specific binding, or both.
