Abstract
Monoclonal antibodies against P0, myelin basic protein, or myelin-associated glycoprotein were generated by fusing mouse myeloma cells with spleen cells from BALB/c mice immunized with central and peripheral nervous system myelin proteins. The antibodies secreted were either IgG, IgM, or IgA. Clone C6B5 (iso-type IgM) secreted antibody(ies) that bound to both myelin basic protein and myelin-associated glycoprotein, although binding of antibody to myelin basic protein as detected by the immunoblot technique appeared to be much less than to the myelin-associated glycoprotein. Antibodies were characterized in solid-phase radioimmunoassay for their species cross-reaction, and histologically for the specificity of binding to myelin in central and peripheral nervous system tissues. These monoclonal reagents should prove valuable in studying CSF and myelin-producing cells, since in both cases the concentration of myelin proteins is low.
