anti-Immunoglobulin M (IgM) secondary antibodies

() is constructed of five or six units (i.e. mostly as pentamers but also hexamers occur) which are each comprised of two heavy-chains (mu-chains) and two light chains, bound together by disulfide bonds and a so-called J-chain. A J-chain is usually, but not always, found in pentameric but not in the hexameric form. It is not yet clear if pentamers without the J-chain fullfill different functions. Each monomer has two antigen binding sites, hence a pentameric has 10 binding sites. is by far largest antibody in the human circulatory system. In its pentamer form has a molecular mass of approximately 900 kDa.

is present on B cells and its main function apparently is the control of B-cell activation. Interestingly, it is also the primary antibody against A and B antigens on red blood cells and responsible for the blood-clotting reaction during blood-transfusion from wrong donors.

is primarily found in serum and due to its size, it cannot diffuse well, and is found in the interstitium only in very low quantities.
