(A) PCR amplification of the ALV-B env gene in DF-1/B cells. (M) DNA marker3; (1): RNA extracted from DF-1/B cells; (2): Genomic DNA extracted from DF-1/B cells; (3) RNA extracted from DF-1 cells. (B) Levels of ALV-B env gene transcription in DF-1/B cells were determined by real-time RT-PCR with gene specific primers. DF-1 cells served as a negative control. Data are representative of 2 independent experiments, both performed in triplicate.
