Results of RT-PCR analysis of mESC lines stably transduced with two recombinant EBV genomes.

(+) indicates detection of cDNA of a given transcript, minus (–) its absence. B95.8 cells serve as positive control for EBV's latent genes. The gene encoding glyceraldehyde 3-phosphate dehydrogenase (GAPDH), is an ubiquitously expressed housekeeping gene, which serve as another positive control for correct cDNA synthesis and PCR amplification. EBV (+) indicates detection of genomic EBV DNA. Primers used are listed in Table S1.
