to ascertain the specificity of such unexpected immunoreactivities for gfap and to exclude possible crossreactivities with other intermediate filament ( if ) proteins , a panel of different antibodies was used for immunocytochemistry with the peroxidase-antiperoxidase ( polyclonal antisera ) or labeled biotin-avidin ( monoclonal antibodies ) techniques : two monoclonal and four polyclonal anti-gfap , three monoclonal and one polyclonal anti-cytokeratins ( ck ) , and two monoclonal anti-vimentin ( vim ) antibodies .
