Parent parasite used to introduce the genetic modification | |
Rodent Malaria Parasite | P. berghei |
Parent strain/line | P. berghei ANKA |
Name parent line/clone | RMgm-1320 |
Other information parent line | This transgenic reporter line expresses luciferase under the control of the eef1α (PBANKA_113330) promoter and, in addition, mCherry under the control of the hsp70 (PBANKA_071190) promoter. Both reporter cassetes are introduced into the silent 230p locus, using a single DNA construct. This transgenic line does not contain a drug-selectable marker |

Additional remarks selection procedure | This reporter mutant expressing mCherry and Luciferase does not contain a drug-selectable marker. The mutant has been generated in the reference line GIMOPbANKA (RMgm-687). The GIMO mother line is used for introduction of transgenes into the modified 230p locus through transfection with constructs that target the 230p locus. These constructs insert into the 230p locus (‘gene insertion’), thereby removing the hdhfr::yfcu selectable marker (‘marker out’) from the genome of the mother lines. Transgenic parasites that are marker-free are subsequently selected by applying negative drug selection using 5-FC. This selection procedure is performed in vivo in mice. | ||||||||||||||||||
