Serum protein electrophoresis. The numbers represent the electrophoretic run of different patients. When the sample is applied and the electric current is turned on, the serum proteins migrate differentially. Then, they are fixed and stained in blue. The most stained band is albumin, followed by alpha 1 globulin, alpha 2 globulin, beta globulin and gamma globulin. Column 6 shows a normal pattern of gamma globulin intensity and width. Column 7 is from the case reported, showing a marked reduction in the gamma globulin region. Column 8 was obtained from a patient with a monoclonal peak just after the beta globulin band and reduced gamma region. Column 3 displays a polyclonal gamma globulin augmentation (polyclonal hypergammaglobulinemia). After staining, the results are read by spectrometry to quantify each band
