Fig. 1. (A–D) Serum protein electrophoresis (SPEP) (left) and immunotyping (IT) (right) profiles of four samples (EP-23-01 (A), EP-23-02 (B), EP-23-03 (C), and EP-23-04 (D)). The serum electrophoresis patterns displayed in this figure were observed via the Capillarys 2 Flex Piercing analyzer (Sebia, Lisses, France). Monoclonal protein was detected in two of the four test samples (EP-23-02 and EP-23-04), and the detection of monoclonal proteins and the isotyping results (immunoglobulin G [IgG] lambda type for sample EP-23-02 and IgG kappa type for sample EP-23-04) were consistent in all participating laboratories.
