These beads have been developed for automatic DNA/RNA separation like genomic DNA, plasmid DNA, total RNA, viral DNA or PCR-products. DNA/RNA bind to the silica surface under high salts conditions (5M guanidinium thiocyanate). The ferromagnetic beads have excellent magnetic properties and are compatible with most automatic DNA separation systems.

Terminal ion-exchange groups are reversibly to charged groups of biomolecules and can be eluted with salt- or pH-gradient. Ion-exchange separation can be used for many applications such as the isolation of proteins, antibodies, DNA/RNA and other biomolecules.
Anion-exchange magnetic particles bind selectively to the negatively charged membrane groups of cells, bacteria or viruses which can be separated by magnetic forces.

Terminal reactive groups allow the convenient and efficient covalent binding of bioaffine ligands. This is a unique feature accounting for the rapidly increasing number and variation of novel and different receptor-affine biological substances.
