Figure 1From: An XMRV Derived Retroviral Vector as a Tool for Gene TransferPromoter activity of XMRV U3 region. The pGL-XMRV-U3-Luc plasmid was used to transfect five cell lines and luciferase activity was compared to the activity of cells transfected with pGL3 SV40-Luc. Data are represented as the mean of triplicates ± standard error (s.e.).Back to article page
