Our year-long experience in manufacturing agarose resin lead to the high yield of 50 mg protein per ml resin, which is leading in the market compared to other Ni-IDA suppliers. Ni-IDA products by Cube Biotech are also available as agarose resin beads for FPLC and batch spin. For your convenience Cube Biotech also offers its own MagBead separator for use with our magnetic beads.
