Additional Information
CaptureSelect RoboColumns™ are small chromatography columns used for fully automated and parallel chromatographic separations on robotic liquid handling workstations.

CaptureSelect KappaXP matrix recognizes the kappa light-chain of human antibodies, enabling purification of all Kappa containing Ig’s, Fab, and Fab2 fragments directly from complex sources and feed streams.

Features of this affinity matrix include
:• Purification of Kappa monoclonal antibodies, Fab, and Fab2 fragments in a single step with high purity and yield
• Mild elution for Fab fragments and antibodies
• Human-specific, no binding to bovine antibodies
• Excellent scalability
• Excellent pH stability up to 100 mM NaOH (limited exposure)
• Non-animal derived

Free of animal components
CaptureSelect products are affinity ligands created using a proprietary technology based on camelid-derived single-domain antibody fragments. The KappaXP ligand is a 13-kDa fragment comprising the three complementarity determining regions (CDRs) that form the antigen binding domain. The ligand is efficiently produced by the yeast Saccharomyces cerevisiae in a production process free of animal components.
