We are pleased to offer a selection of magnetic silica beads that are useful for separation, concentration and purification of biomolecules. These magnetic silica beads are well suited as a solid phase in assay kits. A wide range of customized beads are available with regard to size, kinetics, optical, surface and binding properties. We also offer magnetic bead-based kits for automated purification of nucleic acids and magnetic separators for magnetic separation of magnetic beads from liquid samples.
If you do not see the beads that you are looking for, please contact us.
