The characterization of monoclonal antibodies is a major challenge in process monitoring and quality control. TSKgel® G3000SWXL columns have been the industry standard for quality control of mAbs by SEC for decades. With the introduction of TSKgel UP-SW3000, 2 µm silica-based UHPLC–HPLC columns, increased speed and higher resolution can be achieved for the separation of antibody fragments, monomers, and dimers.
