Comparison with other magnetic beads

The anti-cancer drug methotrexate (MTX) was immobilized on the magnetic beads of each company using the same method, and affinity purification was performed. Compared with the beads of other companies, FG beads® features less non-specific protein adsorption and allowed purification with a higher recovery rate for the DHFR that was the target protein of MTX.
