General description

TSKgel SWXL-type columns contain smaller particles than TSKgel SW-type columns; 5 and 8μm versus 10 and 13μm. As the TSKgel SW-type columns, TSKgel SWXL columns feature highly porous silica particles, the surface of which has been shielded from interacting with proteins by derivatization with ligands containing diol functional groups. TSKgel SWXL-type columns stand out from other silica- or polymer-based high performance size exclusion columns by virtue of their large pore volumes. These columns are commonly used in the quality control of monoclonal antibodies and other biopharma products.
