Identification with monoclonal antibodies of virus-specific DNA-binding proteins in the nuclei of cells infected with three serotypes of Marek's disease virus-related viruses.

Two groups of virus-specific polypeptides were identified in the nuclei of infected cells by cross-reacting monoclonal antibodies with three serotypes of Marek's disease virus. Of these, a 135,000-molecular-weight polypeptide common to all three serotypes was found to bind to both double-stranded and single-stranded DNAs.
