Localization and quantitation of EBV-associated nuclear antigen (EBNA) in Raji cells.
Epstein-Barr virus (EBV)-associated nuclear antigen (EBNA) was localized to chromatin fibers of Raji cells. When EBNA was labeled with the horseradish-peroxidase technique of Sternberger a strong reaction covered most fiber surfaces as observed by electron microscopy. The dry mass of Raji chromatin increased after exposure to both EBV-positive and -negative serum, but the increase was significantly larger in the material treated with positive serum.
