    Diabodies are dimeric antibody fragments. In each polypeptide, a heavy-chain variable domain (VH) is linked to a light-chain variable domain (VL) but unlike single-chain Fv fragments, each antigen-binding site is formed by pairing of one VH and one VL domain from the two different polypeptides. Diabodies thus have two antigen-binding sites, and can be bispecific. Direct structural evidence is lacking for the connections and dimeric interactions between the two polypeptides of the diabody.
