TL;DR: High-resolution two-dimensional electrophoresis was used to analyze kappa-type monoclonal immunoglobulin light chains in urine of two patients with multiple myeloma, finding acid isoforms of kappa chains, pI < 4,95, which had not been present in the urine of these patients before.
Abstract: High-resolution two-dimensional electrophoresis was used to analyze kappa-type monoclonal immunoglobulin light chains in urine of two patients with multiple myeloma. The patients were treated, remission lasted about 2.5 years. In the period of relapse of the disease, acid isoforms of kappa chains, pI < 4,95, which had not been present in the urine of these patients before, were found in urine of both patients. Kappa-type Bence-Jones protein in urine of one patient showed unusual behavior: It failed to precipitate in the range of 40-60 degrees C or on boiling.

TL;DR: High-resolution two-dimensional polyacrylamide gel electrophoresis (2-DE) was used to analyze more precisely serum and urine specimens of a patient suffering from IgD myeloma associated with renal insufficiency, which strongly suggests amyloidogenicity of these monoclonal light chains.
Abstract: High-resolution two-dimensional polyacrylamide gel electrophoresis (2-DE) was used to analyze more precisely serum and urine specimens of a patient suffering from IgD myeloma associated with renal insufficiency. The application of 2-DE with immobilized pH gradient followed by immunoblotting revealed the presence of acidic monoclonal delta chains, hidden on 2-DE by albumin. This approach also enabled to detect two other forms of delta heavy chains expressing both reduced (45 kDa) and high (110 kDa) mol. weight. The analysis of urine specimen proved the presence of three acidic isoforms of monoclonal lambda light chains together with multiple monoclonal light chain fragments, which strongly suggests amyloidogenicity of these monoclonal light chains.
