Characterization of EBV-negative BL cell lines and EBV-positive converts infected with an EBNA2 gene-deleted recombinant EBV. A. Western blot analysis for expression of EBNA1, -LP, -2, and -3C and LMP1; the EBV-negative B-cell lymphoma line BJAB was used as a negative control, and the X50-7 LCL was used as a positive control for blotting. B. Results of apoptosis assays 48 h after ionomycin treatment; Sav-BL was used as a reference latency I BL line. Error bars indicate standard deviations.
