title: An improved, ultrasensitive method for the detection of IgM oligoclonal bands in cerebrospinal fluid.
abstract: A new, 10-fold more sensitive method, based on an improved immunofixation technique, has been devised to detect oligoclonal IgM bands in unconcentrated cerebrospinal fluid (CSF). Using agarose gel electrophoresis, 5 microliters of an unconcentrated sample containing oligoclonal bands was separated and blotted on to a polyvinyldifluoride membrane. To visualise the pattern, a peroxidase-labelled double-antibody technique was used. No prior concentration of CSF was needed and the process required only 5 h. The technique may prove very useful in diagnosing an early intrathecal immune response.
