Crossed immunoelectrofocusing for identification of normal and abnormal cerebrospinal fluid proteins. A preliminary report.
Isoelectric focusing is a valuable method for the analysis of cerebrospinal fluid (CSF) proteins. Its high resolving power has, however, created problems in identifying the large number of protein bands separated. In an attempt to identify these bands, two-dimensional crossed immunoelectrofocusing has been used, where isoelectric focusing is combined with rocket immunoelectrophoresis. By these methods 9 of the normal proteins in the acidic pH interval have been identified. In addition the unusual CSF protein abnormalities occurring in Marie-Sanger-Brown's ataxia and alcoholic cerebellar degeneration have been shown to represent increases of different microheterogeneous forms of transferrin.
