WebSerum protein electrophoresis (SPEP) is the most commonlyusedlaboratory testfor the detectionof monoclonal proteins. Serum proteins are loaded on to a gel or a capillary tube and are separated by an electrical current based on charge and size. The proteins are then stained for visualization. The proteins migrate into five zones or fractions. These WebIn contrast, SPEP is capable of estimating the concentration of an M protein. In multiple myeloma, sometimes only free light chains are produced. The concentration of the light chains in serum may be so low that these light chains remain undetected using SPEP and even serum immunofixation.
