The mobility of the immunoglobulins G, A and M, beta-trace protein and gramma-trace protein on isoleectric focusing of serum and CSF was determined by immunofixation using specific antisera. Polyclonal IgG migrated as multiple bands between pH 4.7--8.6, polyclonal IgA as multiple bands between pH 4.9--6.1 in CSF and serum. IgM could not be identified in normal CSF or serum. beta-trace protein gave three bands at pH 8.0, 8.4 and 7.4--7.5, respectively, while gamma-trace protein gave one single band at pH 9.5--greater than 9.5. Oligoclonal IgG in CSF in multiple sclerosis and neurosyphilis migrated between pH 8.6--greater than 9.5 and was easily discriminated from other proteins.
