Figure 167.4

Immunoelectrophoresis. Serum from a normal control was placed in the top well and the patient's undiluted serum was placed in wells 2, 3, 5, and 7, reading down. Wells 4, 6, and 8 contained a 1:5 dilution of the patient's serum. The top trough contained antibodies to whole human serum. The third trough contained antibodies to human IgG; the fifth trough, antibodies to human IgA; and the seventh trough, antibodies to human IgM. The varied positions of the precipitin bands indicate the differences in migration of the proteins in an electric field.
