Oz Biosciences has developed the innovative technique of magnetic transfection, or Magnetofection. The principle of Magnetofection is to associate nucleic acids, transfection reagents or viruses with specific magnetic nanoparticles. The resulting molecular complexes are then concentrated and transported into cells supported by an appropriate magnetic field. Unique Magnetofection transfection reagents are available for DNA, siRNA and viral vectors including retroviruses and lentiviruses. Lipofection transfection reagents are also available. These reagents combine and exploit the properties of cationic lipids and polymers to achieve an extremely efficient DNA delivery into cells.
