Rapid, accurate and cost-effective quantitation of monoclonal antibodies (MAbs) is essential for bioprocessing. High Pressure Liquid Chromatography (HPLC) and the Octet® are some of the commonly used techniques for MAbs titer determination. To ensure MAbs purification column efficiency, the dynamic binding capacity (DBC) of Protein A for Mab can be determined by loading feedstock onto the column until binding sites for the MAb become saturated and MAb begins to break through. An assessment of the relative merits of Protein A…
