Both Classical (MC catalog codes) and Encapsulated (ME catalog codes) superparamagnetic microspheres are synthesized using a process that results in the distribution of iron oxide crystals throughout the polymer matrix. The surfaces of Encapsulated magnetic microspheres are expected to be free of iron oxide, while the Classical version will have some exposed iron oxide. COMPEL microspheres (UMC catalog codes) are highly uniform and spherical. Fluorescent magnetic microspheres are available as ~1% solids (w/v) aqueous suspensions in four standard volumes: 1mL, 5mL, 10mL, and 100mL. See the use of our microspheres for cell labeling and MRI tracking in TSD 0748.
