title: Presence and absence of virus particles in hybridomas secreting monoclonal antibodies against gliomas.
abstract: Hybridoma clones were produced by fusion of splenocytes from glioma-immunized hosts and the X63-Ag8.653 mouse myeloma line and Y3-Ag.1.2.3. rat myeloma line. Oncornavirus particles were found in all clones descending from the mouse myeloma line. No virus particles could be found in either the spleens of immunized Balb/c mice and Fischer rats or in the rat myeloma line and the hybridomas derived from it.
