Features and Benefits

m-dPEG37-acid is a long (112 atoms, 133.9 Å), methyl-capped, discrete chain length polyethylene glycol (dPEG) spacer. The reactive end of the molecule terminates in a propionic acid group. m-dPEG37-acid reacts with amine-functionalized surfaces (carbon nanotubes, nanoparticles made of silica or various metals, quantum dots, and similar types of products) or free amines on biomolecules. m-dPEG37-acid is a monodisperse equivalent of the polymeric PEG1500. When used to coat surfaces or modify biomolecules, m-dPEG37-acid reduces or eliminates non-specific binding and increases water solubility.
