Antisera to chicken brain antigen (CBA) isolated by hydroxyapatite chromatography from 8 M urea extracts following repeated extractions with phosphate buffer selectively decorate neurofilaments (NF) in neuronal perikarya, dendrites and axons. The antisera also reacted with GFA protein, the astrocyte-specific intermediate filament protein, as indicated by the adsorption of NF immunoreactivity following passage of the antisera through columns prepared with purified GFA protein. Moreover, the antisera stained the polypeptides of the NF triplet (70 kd, 150 kd, 200 kd) and GFA protein by the immunoblotting procedure. Monoclonal antibodies selectively decorating NF in tissue sections were isolated from a fusion of mouse myeloma cells with spleen cells of mice immunized with CBA. By the immunoblotting procedure the antibodies decorated the 150 kd NF polypeptide and GFA protein. No staining of glial filaments or any other structure on tissue sections was also observed with antibodies derived from another fusion strongly reacting with GFA protein on immunoblots. All antibodies (monoclonal and polyclonal) appeared to react with the same region of the GFA polypeptide as indicated by immunoblots of cleavage products.
