Figure 2From: Transgenic Plasmodium parasites stably expressing Plasmodium vivax dihydrofolate reductase-thymidylate synthase as in vitro and in vivo models for antifolate screeningSouthern analysis of transgenic parasites to confirm allelic replacement of dhfr-ts of Plasmodium falciparum (A) and Plasmodium berghei (B) with dhfr-ts gene from P. vivax. DNA probes specific to Pvdhfr-ts (PvDT), Pfdhfr (PfD) and 3'UTR of Pbdhfr-ts (3'UTR PbDT) were used to detect restriction-digested fragments from genomic DNA of transgenic parasites. Pl: pCBVD plasmid control; K1: P. falciparum K1CB1; B2: Transgenic PfPvDTclB2; PbGFP: P. berghei GFP; WT: transgenic PbPvDTcl4; SP: transgenic PbPvSP21cl2.Back to article page
