WebOligoclonal bands are defined as at least two bands seen in the CSF lane with noncorresponding band present in the serum lane. Thus, it is crucial to perform CSF and serum electrophoresis simultaneously. Oligoclonal bands may be found in 95% or more of patients with clinically definite MS [36]. WebOligoclonal Banding: The oligoclonal banding assay requires paired cerebrospinal fluid (CSF) and serum samples. Unconcentrated CSF and diluted serum are electrophoresed by isoelectric focusing. The separated IgG bands are visualized by an IgG immunoblot, and oligoclonal bands that are present in the CSF and not in the serum are reported.
