SiMAG particles are magnetic silica beads with superparamagnetic or ferromagnetic properties and possess either a highly porous or a non-porous silica surface.

The beads are available with diameters of 0.5 µm to 1 µm and are easily separable by magnetic batch procedures.

The surface area provides a high binding capacity of biomolecules such as purified DNA/RNA or of bioaffine ligands, e.g. antibodies or proteins.

SiMAG beads have an inert and stable solid-phase silica matrix without autofluorescence and are autoclaved for sterile applications.

SiMAG beads can be used for ion-exchange, hydrophobic or covalent binding of biological substances due to the chemical modification of the silica surface with a variety of functional groups.

The hydrophilic character, the mechanical stability, the resistance to microbiological degradation, and excellent reproducibility are SiMAG's major advantages in biotechnology applications.
