Briefly, the transfection mixture consisting of 20 µL of packed RBCs, 5 µg of each plasmid DNA (1 µg/µL) (Qiagen plasmid Maxiprep kit), and of 70 µL of Amaxa SE solution, resulting in a final volume of 100 µL, was prepared at room temperature (RT). The transfection mixture was transferred to an Amaxa Nucleocuvette (Lonza), and transfections were performed at RT using an Amaxa 4D-Nucleofector. After applying the CM-162 pulse, electroporated RBCs were processed as mentioned above. Culture media were changed daily and selection drugs (2.5 µM Blasticidin HCl and 200 µg/mL Geneticin) were added 24 h after electroporation and maintained continuously
in the asexual cultures, unless stated otherwise. Once parasites were observed (day 18), parasites were cloned by minimal dilution in 96-well plates.
