Gold Nanoparticle Biotin Conjugate
Our 40nm gold nanoparticle Streptavidin conjugate is manufactured using special conjugation technology. We have coated our high quality gold nanoparticles with a proprietary surface coat that covalently binds the biotin forming ultra stable conjugates. The resulting GOLD Streptavidin nanoparticles can irreversibly bind biotin, meaning that there is no desorption of the antibody from the gold particle, which is a common problem associated with gold conjugates when developed using passive adsorption techniques.
