Figure 4. Generation of P. falciparum mei2/linup dual gene deletion strain (PfLARC2).

Figure 4

(A) PfLARC2 was created by first deleting Pf Mei2 on chromosome 6 and then Pf LINUP on chromosome 12 using plasmids pFC-yFCU-Plasmei2 and pFC-yFCU-LINUP, respectively. Sequential positive and negative selection with WR99210 and 5FC resulted in marker-free PfLARC2 free of extraneous DNA. Primers used for confirming parasite genotypes are shown as letters. Expected amplicon sizes for WT and PfLARC2 and the pFC plasmid are indicated in the schematic. Agarose gel electrophoresis to confirm, (B) gene deletion of PlasMei2, (C) gene deletion of LINUP, and (D) lack of plasmid in three PfLARC2 clones F7, C12, and B7, respectively. Source data are available online for this figure.
