Description

General description

The TSKgel SuperSW and UltraSW mAb columns consist of three specialized columns designed for the separation and analysis of monoclonal antibodies (mAb). While mAbs can be analyzed using many different modes of HPLC, size exclusion is best for aggregation, dimer, and fragmentation, making it the best method for heterogeneity studies.TSKgel SuperSW mAb HTP columns provide high throughput analysis of mAb monomer and dimer and is UHPLC compatible. These short, narrow bore (15 cm x 4.6 mm ID) silica-based stainless steel columns offer reduced lot-to-lot variation, long column life, reduction of unspecified adsorption, and superior recovery of aggregates. The TSKgel SW mAb HTP columns utilize a unique pore-controlled technology, which produces a shallow calibration curve in the molecular weight region of a typical monoclonal antibody.
