Protein G Gold Nanoparticle Conjugate
Our 20nm gold nanoparticle Protein G conjugate is manufactured using our InnovaCoat® technology. We have coated our high quality gold nanoparticles with a proprietary surface coat that covalently binds the Protein G, forming ultra stable conjugates. The attachment is irreversible meaning that there is no desorption of the antibody from the gold particle, which is a common problem associated with gold conjugated developed using passive adsorption techniques. InnovaCoat® GOLD Protein G 20nm binds to the Fc region of most mammalian IgG’s. Binding specificities and affinities can vary depending on source species and antibody subclasses.
