The SPHERO Magnetic Particles are produced by coating a layer of magnetite and polystyrene on monodispersed polystyrene core particles. This rezults in particles of spherical in shape, paramagnetic in nature and uniformal in size. The magnetite contents of the magnetic particles can be a subject of further adjustment but usually it is in the range of 10% to 15% for 1 micron particle surfice. Separation from a suspension can be easily performed magnetically. When removed from the magnet the particles will become non-magnetic. Even after repeated exposure to a strong magnetic field the particles will not retain detectable magnetism. The SPHERO Magnetic Particles have a wide range of uses such as cell separation, affinity purification, DNA probe assays, magnetic particle EIA, etc.
Flow cytometer type
These particles can be used for calibration with BD FACSes like FACSCalibur, FACSCanto, Beckman Coulter Flow Cytometer, Becton Dickinson FACScan, Becton Dickinson Flow Cytometers, Miltenyi cytometer, Millipore Flow Cytometers and Millipore Guava.
