Oligoclonal band
（重定向自Oligoclonal bands）
Oligoclonal bands are bands of immunoglobulins that are seen when a patient's blood serum, gained from blood plasma, or cerebrospinal fluid (CSF) is analyzed.
Two methods of analysis are possible: (a) protein electrophoresis, a method of analyzing the composition of fluids, also known as "agarose gel electrophoresis/Coomassie Blue staining", and (b) the combination of isoelectric focusing/silver staining. The latter is more sensitive.
