WebJul 30, 2024 · IgM consists of five four-chain structures (20 total chains with 10 identical antigen-binding sites) and is thus the largest of the antibody molecules. IgM is usually the first antibody made during a primary response. Its 10 antigen-binding sites and large shape allow it to bind well to many bacterial surfaces. WebDec 13, 2024 · In contrast to normal or reactive B-cells, mature B-cell lymphoid neoplasms are clonal, expressing only a single Ig species and thus are monotypic for either kappa or lambda light chain (i.e., light chain restricted) (Fig. 1C). Therefore, detection of monotypic B-cells is an important tool for the identification of mature B-cell neoplasms.
