A Case of Multiple Myeloma with Unusual Serum Protein Electrophoresis

Monoclonal gammopathy is a group of B-cell disorders resulting in the secretion of a specific and unique monoclonal immunoglobulin (M-component); best detecting with high resolution agarose gel electrophoresis. An M-protein is usually visible as a localized band on agarose gel electrophoretic peak in the beta, gamma, or rarely in the alpha-2globulin region of the densitometer tracing. Here, we presented a multiple myeloma patient with IgA kappa paraprotein showing an M spike in the alpha-2 globulin region in agarose gel electrophoresis. Pulse Vol.8 January-December 2015 p.77-80
