name: IgA2 immunoglobulin complex, circulating (human)
def: "An IgA immunoglobulin complex, circulating in human that is composed of two identical immunoglobulin heavy chains of the secretory isoform of the IgA2 isotype and two identical immunoglobulin light chains (kappa or lambda), held together by disulfide bonds, sometimes complexed with J chain or J chain and secretory component, and present in the extracellular space, in mucosal areas or other tissues, or circulating in the blood or lymph." [PRO:ADD, PMID:16362985, GOC:add, ISBN:0781765196]
comment: Category=organism-complex. Requested by=HIPC. Requested by=CL. Note: Human circulating IgA2 is only found as a monomeric form.
