Anti-gliadin antibodies are produced in response to gliadin, a prolamin found in wheat. In bread wheat it is encoded by three different alleles, AA, BB, and DD. These alleles can produce slightly different gliadins, which can cause the body to produce different antibodies. Some of these antibodies can detect proteins in specific grass taxa such as Triticeae (Triticeae glutens), while others react sporadically with certain species in those taxa, or over many taxonomically defined grass tribes.Antigliadin antibodies can be generated in mice or rabbits by immunizing whole purified gliadins, proteolytic fragments of gliadin, or synthetic peptides that represent epitopes of gliadin. After developing an immune response, B-cells from mice can be fused with immortalizing cells to form a hybridoma that produces monoclonal antibodies (Mab). Mab can be expressed in culture or via ascites fluid production to produce large amounts of a single antibody isoform.
