Solid-phase radioimmunoassay for detection of antibodies to myelin basic protein.

A solid-phase double-antibody radioimmunoassay was developed for the detection of anti-myelin basic protein (BP) in sera. Antigen was adsorbed to glass test tubes, reacted with rat anti-BP sera, followed by 125I-labeled rabbit anti-rat IgG. This assay was capable of detection of specific antibody at low nanogram per ml levels, was technically simple, and the results correlated well with established procedures.
