Rodent Malaria ParasiteP. yoelii
Parent strain/lineP. y. yoelii 17XNL
Name parent line/clone RMgm-689
Other information parent lineRMgm-689 is a reference P. yoelii 17XNL line (1971cl1) that expresses the fusion protein GFP-Luciferase under the control of the constitutive P. berghei eef1a promoter. The transgene expression cassette is introduced into the 230p locus. This line does not contain a drug-selectable marker.

Additional remarks genetic modificationThis mutant was generated in the reference line 1971cl1 (see above) by standard methods of transfection using a DNA construct that targets the fabb/f gene by double cross-over integration. The 5’- and 3’- fabb/f target regions were amplified using primers 7358 5’-atgggcccTTGCGCTATTTATAAGAGTTTGAGAGG / 7359 5’-aaggcctCAAGAATATTTTTAAGGGCCATTTC and 7360 5’-ccggggtaccCAATGATTGCAAATACACCATCAG / 7361 5’-ataagaatgcggccgcGTGGATATACGCAAGTGTGCGAG and cloned up (ApaI/StuI) and downstream (KpnI/NotI) of the hdhfr/fcu selectable marker cassette of plasmid pL0034. The final DNA construct was linearized with HindIII/EcoRI before transfection.
