EBV displays a latency II gene-expression pattern in ENTKL- and CAEBV-derived cell lines. (A) Heatmap summary of EBV transcript levels to compare between the different cell lines. Data shown were normalized to the levels of PGK1 transcripts. (B) Expression levels of key viral proteins, LMP1 and EBNA2, at steady state were assessed by western blot analysis. Probing for HSP70 was used as a protein loading control and BL cell lines, BL41 and Raji, and a lymphoblastoid cell line (LCL) were included as controls. Representative blots are shown.
