Thorough characterization of monoclonal antibodies includes the identification and monitoring of acidic and basic isoforms. The Agilent Bio MAb HPLC columns feature a unique resin specifically designed for high-resolution charge-based separations of monoclonal antibodies. Bio MAb columns are available in 1.7 µm, 3 µm, 5 µm, and 10 µm sizes, providing higher resolution with the smaller particles. The Bio MAb column features a highly uniform, densely packed, weak cation exchange layer. This layer of the Bio MAb column is chemically bonded to the hydrophilic, polymeric coating of the Bio MAb column.
