Our 20nm gold nanoparticle Protein A 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 A 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 conjugates developed using passive adsorption techniques. InnovaCoat® GOLD Protein A 20nm binds to the Fc region of most mammalian IgG’s. Binding specificities and affinities can vary depending on source species and antibody subclasses.
