Our year-long experience manufacturing agarose resin led to the high yield of 80 mg protein per ml resin, leading in the market compared to other Ni-NTA suppliers. Ni-NTA products by Cube Biotech are also available as agarose resin beads or as XL magnetic beads. For convenience, Cube Biotech also offers a MagBead separator for use with our magnetic beads.
