[The role of various methods of electrophoresis in the diagnosis of paraproteinemia].

For the estimation of different electrophoresis methods for indication and identification of paraproteins as routine methods are proposed the cellulose acetate electrophoresis and the fixation immunoelectrophoresis in cellulose acetate foils. Under adequate conditions the agar gel electrophoresis working with larger separability can be used together with immunochemical investigations. In examinations of uroproteins and also for the identification of rare and atypical cases of paraproteinaemia (narrower and several M-gradients, immunoglobulin fragments and complexes) in connection with the methods mentioned also the electrophoresis in the polyacrylamide gel (PAG and in the system PAG-SDS) can represent a valuable information.
