PureCube Ni-IDA 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: >40 mg/ml
• Bead Ligand: Ni-IDA
• Bead size: 90 μm
• Filling quantity: Delivered as a 25% suspension
• pH stability: 2 to 14
• Chelator stability: Stable in buffer containing 10 mM DTT and 1 mM EDTA
• 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 lead to the high yield of 40 mg protein per ml MagBeads. The XL beads are meant for viscous media and cell debris.
