Capillary zone electrophoresis and immunotyping of Case 1. (a) Capillary zone electrophoresis showing a peak in the beta1 region and a minor peak in the alpha region. (b) Immunotyping showing a subtraction by the anti-IgG antibody, without a corresponding region in the light chain region, identifying a gamma chain peak. Ref: protein electrophoresis. IgG: immunosubtraction with anti-IgG antibody; IgA: immunosubtraction with anti-IgA antibody; IgM: immunosubtraction with anti-IgM antibody; K: immunosubtraction with anti-kappa antibody; L: immunosubtraction with anti-lambda antibody.
