No exposed iron oxide on the surface of the beads makes them beneficial in applications where exposed iron oxide causes undesirable interferences. The secondary antibodies coupled to the surface of particles are affinity purified and cross-adsorbed to achieve minimal cross-reaction with other immunoglobulins. These particles are paramagnetic in nature and perform rapid magnetic responsiveness. With low non-specific binding, the beads are ideal for immunoassays, immunoprecipitation, IP-western blots, cell isolation, protein purification, etc.Immunoassay, Immunoprecipitation, Cell Isolation, Antibody/Protein Purification
