Magnetic particles of ExtraGen

The magnetic sorbent ExtraGen® is an aqueous suspension of solid-phase magnetic particles based on iron oxide and silicon oxide. It is designed to isolate nucleic acids from clinical and biological samples. The suspension of the magnetic sorbent has an "intermediate" sedimentation stability, which is especially important when using the material in automatic DNA isolation systems. ExtraGen® particles are resistant to heat, strong oxidants and intense mechanical influences (centrifugation, dispersion, etc.). The use of proprietary buffer solution allows the particles to be stored at room temperature for a year without deterioration of their sorption properties. As tests have shown, the ExtraGen® sorbent shows high efficiency in the isolation of nucleic acids both in manual mode and with the use of automatic stations.
