Affimag Magnetic Polystyrene Microspheres

Polystyrene magnetic microspheres are prepared by coating a thin layer of iron oxide shell onto polystyrene core particles (PSC) or embedded the iron oxide in polystyrene microspheres (PSE). They are particularly useful in cell separation, protein purification, and immunoassays.
