Large surface area combined with higher magnetite content (~15%) make them ideal solid phase for use in cell separation, magnetic removal of microorganisms, viruses and cross reactants in serum, as well as, affinity purification applications in fast magnetic response time.DNA/RNA Purification, Immunoassay
