CaptureSelect™ KappaXL Affinity Matrix, available here in a pre-packed column format, has been specifically designed for the purification of recombinant human Ig’s (including IgA, IgM, IgD, and IgE) containing a Kappa light chain and their Fab fragments.

Features of this affinity matrix include:
• Mild elution for Fab fragments and antibodies
• Human specific (e.g., no binding to bovine antibodies)
• Excellent scalability
• Non-animal-derived

CaptureSelect™ KappaXL Affinity Matrix purifies Ig’s, Fab, and Fab2 fragments directly from complex source materials in a single step with high purity and yield.

Free of animal components
CaptureSelect™ products are affinity ligands created by a proprietary technology based on Camelid-derived single-domain antibody fragments. The ligand is a 13 kDa single-domain fragment comprising the 3 CDRs that form the antigen binding domain, efficiently produced by the yeast Saccharomyces cerevisiae in a production process free of animal components.
