Two Cases of γ-Heavy Chain Disease and a Review of the Literature

Figure 6

Capillary zone electrophoresis and immunotyping of Case 2. (a) Capillary zone electrophoresis prior to the appearance of the gamma heavy chain. A peak identified as the IgMkappa protein is detected in the gamma region. (b) Capillary zone electrophoresis identifies a broad peak in the beta region, identified as gamma heavy chain by immunotyping. (c) Immunotyping identifies a gamma heavy chain without a corresponding light chain and an IgMkappa paraprotein.
