Amino Magnetic Particles, Crosslinked

The SPHERO Cross-Linked Magnetic Particles are prepared to render them resistant to common organic solvents such as acetone, acetonitrile, DMF and chloroform. Since these particles are manufactured by coating a layer of polymer onto the surface of iron oxide crystals, they are not uniform in size and are essentially non-spherical in shape. Their overall size ranges from ~1.0 - 2.0 um. However, cross-linked magnetic particles have significantly greater surface area and higher magnetite content (70%) compared to the 4.0 um uniform magnetic particles. Large surface area combined with higher magnetite content make SPHERO Cross-Linked Magnetic Particles ideal solid phase for use in cell separation, magnetic removal of microorganisms, viruses and cross reactants in serum, as well as affinity purification applications.
