The CaptureSelect™ Bovine IgA Affinity Matrix has been designed specifically for the purification of bovine IgA from whey.

Features of this affinity matrix include:
• binds monomeric, dimeric, and secretory bovine IgA
• one-step purification from whey
• excellent scalability

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