name: secretory dimeric IgA1 immunoglobulin complex (human)
def: "A polymeric IgA1 immunoglobulin complex (human) that is a dimer of secretory IgA1 immunoglobulin complex." [PRO:ADD, PMID:16362985, GOC:add, ISBN:0781765196]
comment: Category=organism-complex. Requested by=HIPC. Requested by=CL. Note that an IgA1 immunoglobulin complex has the function of antigen binding if a suitable antigen is available. Dimeric IgA1 is by far the most common form of polymeric IgA. In human, only the IgA1 isotype is capable of a dimeric form.
