Background: IgA is an immunoglobulin that is typically dimeric and held together by a J-chain protein. IgA is typically found near the mucous membranes of the body, including the gut, respiratory system, eyes, and colostrum. Also exists in a secretory form (in mucosal regions) vs. serum IgA, which is found in serum.
