It is capable of binding to the Fc portion of immunoglobulins, especially IgG from a large number of species. Protein-A may be conjugated with various reporter molecules, including colloidal gold, without affecting the antibody binding site on the molecule. Protein A is immobilized on the nanogold beads.
