PureCube Co-NTA magnetic beads/MagBeads were developed by Cube Biotech for His-tag protein purification.

• Usage: Specific binding and purification of 6× His-tagged proteins
• Specificity: Affinity to His-tagged proteins
• Binding capacity: >30 mg/ml
• Bead Ligand: Co-NTA
• Bead size: 30 μm
• Filling quantity: Delivered as a 25% suspension
• pH stability: 2 to 14
• Other stabilities: 100% methanol, 100% ethanol, 8 M urea, 6 M guanidinium hydrochloride, 30% (v/v) acetonitrile

Our year-long experience in manufacturing agarose resin led to the high yield of 30 mg protein per ml resin, leading in the market compared to other Co-NTA suppliers. Co-NTA products by Cube Biotech are also available as agarose resin beads for FPLC and batch spin or as XL magnetic beads for more viscous cell media. For convenience, Cube Biotech also offers its own MagBead separator for use with our magnetic beads.
