[Polyacrylamide gel disc electrophoresis in the study of cerebrospinal fluid proteins in inflammatory diseases of the central nervous system Preliminary results].

The present study was designed to evaluate the potential of polyacrylamide disc electrophoresis of CSF proteins as an adjunct to laboratory diagnosis of neurological inflammatory diseases. The results of polyacrylamide and cellulose acetate electrophoresis of 42 CSF samples from control subjects and patients with various inflammatory diseases of CNS are presented. A comparison between results from both techniques is made. The polyacrylamide disc electrophoresis has been found valuable in the study of liquoral proteins with particular attention to gammaglobulins because this resolving power is superior to the other method. However, the Authors emphasize the importance of distinguishing the genetically determined proteins and haptoglobins and of the use of specific criteria in interpretation of a CSF protein pattern.
