| Definition | "A polymeric IgA1 immunoglobulin complex (human) that is composed of two monomeric IgA immunoglobulin complexes linked through both direct disulfide bonds and through a disulfide binded monomer of J chain acting as a bridge. Each IgA1 monomer consists of two identical immunoglobulin heavy chains of the secretory isoform of the IgA isotype and two identical immunoglobulin light chains (kappa or lambda), held together by disulfide bonds. Dimeric IgA1 is sometimes complexed additionally with secretory component, and present in the extracellular space, in mucosal areas or other tissues, or circulating in the blood or lymph."

| Comment | Requested by=HIPC. Requested by=CL. Dimeric IgA1 is by far the most common form of polymeric IgA1. In human only the IgA1 isotype is capable of a dimeric form. |
