Company description
Because spherical gold nanoparticles have a strong adsorption function for proteins, they can be non-covalently bound to immunoglobulins, bovine serum albumin, various antibodies, etc., and thus become very useful tools in basic research and experiments. Gold nanoparticles labeled Antibody is basically prepared by using antibodies at their isoelectric point, which can be easily adsorbed on the surface of the nanoparticle under the action of electrostatic force, and incubating them with a high concentration of antibody and gold nanoparticle solution. There are also covalent strategies to link the mediator linker or the antibody directly to the surface of the gold nanoparticles through the antibiotic protein system.
