title: Unchanged expression of Epstein-Barr virus-determined nuclear antigen-1 in productive virus cycle.
abstract: The level of the Epstein-Barr virus (EBV)-determined nuclear antigen (EBNA-1) encoded by the Bam HI-K fragment of EBV DNA remained unchanged in P3HR-1 cells after induction of the productive cycle of virus replication by sodium-n-butyrate and 12-o-tetradecanoylphorbol-13-acetate (TPA). This was shown by the same capacity of cell-free extracts from untreated and treated P3HR-1 cells to absorb anti-EBNA-1 antibody from a known human serum.
