Our PureCube ZN-NTA (zinc-NTA) magnetic beads / MagBeads were created to full fill two purposes: Protein purification of proteins tagged with the poly-his tag. But their key feature: The enrichment of zinc-ion-binding proteins, e.g. the zinc-finger proteins. As an alternative to magnetic beads Cube Biotech also offers Zn-NTA agarose resin beads for batch spin columns & FPLC. This agarose resin can also be bought pre-filled into FPLC columns.
