Description
CaptureSelect™ FcXL Affinity Matrix has been specifically designed for the purification of recombinant human IgG, Fc fusion proteins, and plasma derived IgG. It recognizes the CH3 domain of all human IgG subclasses (IgG1, 2, 3, and 4).Features of this affinity matrix include:
• Mild elution, making it suitable for Fc fusion proteins
• Human specific, no binding to bovine antibodies, for example
• Excellent scalability
• Non-animal-derived
CaptureSelect™ FcXL Affinity Matrix purifies IgGs and Fc fusion proteins directly from complex source materials in a single step with high purity and yield.
Free of Animal Components
Our 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.
