Isoelectric focusing (IEF) and isotachophoresis (ITP), two methods with excellent separation capacities, have been adapted during recent years for the analysis of CSF proteins. The fractions separated by these techniques can be further studied by e.g. immunological methods. ITP has besides its high separation capacity several valuable advantages: very small samples are needed, unconcentrated CSF can be examined, the analyses are quickly performed and the results are immediately obtained on a recorder.

Examinations by thin-layer IEF in a series of about 2,000 patients have afforded much new information about the CSF and serum proteins in many neurological diseases. Different complex CSF protein aberrations have been found in the gammaglobulin range as well as in more anodal positions in MS, infectious neurological diseases and Guillain-Barré syndromes. These aberrations are probably the result of several interacting factors, e.g.the temporal and spatial characteristics of the disease, the release of decomposition products from destroyed tissues, the genetically determined reactivity of the individual and the type of etiological agent.
