Figure 1 Immunoglobulin D-λ/λ myeloma proteins detected by electrophoresis (France, Sebia, HYDRASYS). A: Serum protein electrophoresis showed two slight M-spikes that corresponded to alpha-2 and gamma globulins regions; B: Serum immuno-fixed electrophoresis [detected by anti-immunoglobulin (Ig) G, anti-IgA, anti-IgM, anti-κ, and anti-λ] presented two bands in anti-λ lane but no corresponding heavy chain band; C: Serum immuno-fixed electrophoresis (detected by anti-IgD, anti-IgE, anti-κ, and anti-λ) showed two M bands corresponding to IgD λ and free λ-light chains.

Figure 3 Flow cytometry (BD FACSDiva 8. 0.2) suggested an elevation of monoclonal plasma cells (70.12% of total nucleated red blood cells). All of the monoclonal plasma cells expressed CD229, CD38, and cytoplasmic lambda and partly expressed CD138. FITC: Fluorescein isothiocyanate; UL: Upper left; UR: Upper right; LL: Lower left; LR: Lower right.
