Description
Quantity: 500 mL
Unit Size: Each
Features of this affinity matrix include:
• Purification of all IgA serotypes: IgA1, IgA2, dimeric IgA, and S-IgA (secretory IgA)
• IgA purification from plasma, serum, and recombinant sources
• Efficient purification of IgA with high yields and retained activity
• Excellent scalability
• Non-animal-derivedCaptureSelect IgA-XL Affinity Matrix binds to the Fc part of IgA. The high selectivity and yields obtained using IgA-XL Affinity Matrix enable a robust, fast, and efficient purification process with excellent purity obtained in one step.Animal origin statementCaptureSelect products contain affinity ligands based on recombinant single-domain antibody fragments (VHH) created by a proprietary technology. The VHH affinity ligand is a 12–15 kDa fragment comprising the three complementarity-determining regions (CDRs) that form the antigen-binding domain, efficiently produced in the yeast Saccharomyces cerevisiae by a production process free of any animal components (animal origin-free).Main characteristics
