Case Report
Two Cases of γ-Heavy Chain Disease and a Review of the Literature
Figure 3
Urine electrophoresis and immunofixation. (a) Case 1: urine electrophoresis revealing a broad band and a minor band in the heavy chain region, without a corresponding band in the light chain region. (b) Case 2: urine electrophoresis revealing a broad band in the heavy chain region without a corresponding band in the light chain region. A further kappa light chain band is observed, corresponding to the IgMkappa band identified in the serum. ELP: reference track showing sample proteins; GAM: trivalent antiserum against gamma, alpha, and mu heavy chains; K and L: antisera against bound kappa and lambda light chains; KI and LI: antisera against free kappa and free lambda light chains.
