Protein Electrophoresis, Urine

Urine proteins can be grouped into 5 fractions by protein electrophoresis: Albumin, Alpha-1, Alpha-2, Beta-globulin and Gamma globulin. The electrophoretic pattern and the presence of a monoclonal immunoglobulin light chain may be characteristic of monoclonal gammopathies such as multiple myeloma, primary systemic amyloidosis, and light-chain deposition disease.
