Abstract:
The objective of this study was to investigate the diagnostic significance of serum protein electrophoresis and immunofixation electrophoresis detection in diagnosis of multiple myeloma (MM). One hundred and five patients were investigated. The detection rate of M protein by immunofixation electrophoresis detection was better (105 cases, 100%) than that of serum protein electrophoresis (101 cases, 96.19%, p<0.001). The M band was not detected by serum protein electrophoresis in four cases (3.81%), among which one case (0.95%) was identified as IgA type and 3 cases (2.86%) as light chain type after immunoglobulin analysis. Immunofixation electrophoresis detection technique can be used for screening M protein in patients with atypical MM; and immunofixation electrophoresis detection technique can increase the diagnosis accuracy in patients with atypical MM. Key Words: Multiple myeloma (MM), Serum protein electrophoresis, Immunofixation electrophoresis, Monoclonal immunoglobulin.

Two-dimensional Gel Electrophoresis
The first dimension separation uses the isoelectric focusing or IEF technique performed on immobilized pH gradient (IPG) strips that separate proteins according to their isoelectric points.

Western Blotting
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.
