Cerebrospinal fluid oligoclonal bands in the diagnosis of multiple sclerosis. CSF is used in the diagnosis of multiple sclerosis (MS) by identifying increased intrathecal IgG synthesis qualitatively (oligoclonal bands). Accessibility Immunofixationconsists of an electrophoresis phase and a fixation phase. Increased intrathecal Ig synthesis may occur in other inflammatory CSF diseases and, therefore this assay is not specific for MS. -, Ann Neurol. Both serum and spinal fluid are required. government site. [12] an additional assay for the identification of IgD or IgE must be performed. The separated immunoglobulins (Ig) are visualized by an IgG immunoblot, and OCBs that are present in the CSF and not in the serum are reported. Oligoclonal bands are visible as an increased concentration of restricted bands of IgG after isoelectric focusing and immunofixation of IgG. The assay uses reagents from Helena Laboratories.
