Size Distribution of Serum IgA Antibodies to Food Proteins: Bovine Beta-Lactoglobulin (BLG), Bovine Serum Albumin (BSA) and Gliadin (GL)
As IgA is the main immunoglobulin of mucosal surfaces, IgA antibodies are formed in response to antigens encountered in the gastrointestinal tract, such as food substances. Previous studies have shown that the sera of normal individuals often contain antibodies of IgA, as well as IgG and IgM isotypes, against a variety of dietary substances (1,2). Such antibodies (particularly antibodies to gluten), are also often detected in sera of patients with coeliac disease (3).
