Zusammenfassung
Harnproben von 10 Patienten mit multiplem Myelom und Proteinurie wurden in der SDS-PAGE untersucht. Leichtkettenproteine vom Bence Jones (B.J.) Typ wurden in 7 Fällen als Monomere (M.G. 20–26×103 Dalton), in 2 Fällen als Monomer-Dimer-Gemisch und in einem Fall als Dimer ausgeschieden. Durch SDS-PAGE in der 1. Dimension und nachfolgende Elektrophorese in Agarose, die kappa- und lambda-Ketten-spezifische Antikörper enthielt, wurde in einem Fall die immunologische Identität monomerer und dimerer B.J. Proteine nachgewiesen. Das Verfahren der SDS-PAGE hat sich als aufschlußreiche Methode in den Fällen von Myelom erwiesen, in denen neben einem B.J. Protein ein komplettes monoklonales Protein im Urin ausgeschieden wird.
Summary
Samples of the urine of 10 myeloma patients with proteinuria were examined by SDS-PAGE. Light chain proteins of Bence Jones (B.J.) type were excreted by 7 patients as monomer (m.w. 20–26.5 × 103 Dalton, by 2 patients as a mixture of monomer and dimer and by one patient as dimer. By two-dimensional electrophoresis in SDS-PAG and subsequent electrophoresis in agarose containing kappa and lambda chain specific antibodies the immunological identity of monomeric and dimeric B.J. protein of one patient has been shown. The two-dimensional analysis has been proven a valuable procedure in cases with the excretion of complete monoclonal protein and B.J. protein at the same time.
