Fig. 1 Schematic representation of the plasmids used and of the predicted and observed proviral structures. (A) Maps of SFG (with 3′-LTR modified to contain the Xenopus eFlα promoter), NK, and the construct used to confer resistance to puromycin. The locations of primer sets 1 and 2 are indicated, as is the region of SFG that was used as a probe for Southern blots. (B) The expected SFG proviral genome, and the actual SFG proviral genomic structures.
