title: Electrophoretic characterization of a gamma-1-heavy chain disease.
abstract: This report describes a new case of gamma-1-heavy chain disease found in a woman with malignant lymphoproliferative disease. The patient's serum and urine containing gamma-1-heavy chains were analyzed using different electrophoretic approaches, especially two-dimensional electrophoresis and immunoblotting analysis. In a serum sample, five sets of gamma-1-heavy chain spots differing in molecular weight with acidic pI values and one set of more basic gamma-1-heavy chain spots were found. The major group of spots exhibited molecular weight in the range from 29 to 39 kDa. Examination of urine sample proved the presence of the more basic set of gamma-1-heavy chain spots and two acidic groups, including 29 to 39 kDa set.
