Protein A-coated glass beads. Universal support medium for high-performance immunoaffinity chromatography.

High-performance immunoaffinity chromatography (HPIC) is a technique for the fast isolation and quantitation of both antibodies and antigens. Protein A-coated glass beads provide a stable general immobilization support for most immunoglobulin G (IgG) antibodies. In conjunction with the modern expanding repertoire of monoclonal antibodies, HPIC can be applied to the quantitation and isolation of any biological material, in an active form.
