The CaptureSelect™ IgA Affinity Matrix has specifically been designed for the purification of human IgA from recombinant and plasma sources.

Features of this affinity matrix include:

• Platform for all human IgA, binding to IgA1, IgA2 , dimeric IgA, and S-IgA (secretory IgA)
• Excellent scalability
• Non-animal-derived

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.
