Genetic studies of pfptpa and pfpp2a. (a,b) Gene-targeting construct for gene disruption by single homologous recombination using the pCAM-BSD, and the locus resulting from integration of the knockout pfptpa (a) or pfpp2a (b) construct. (c,d) Analysis of pCAM-BSD-pfptpa (c) and pCAM-BSD-pfpp2a (d) transfected 3D7 culture by PCR; lanes 1–3 correspond to DNA extracted from transfected parasites; lanes 4–6 correspond to DNA extracted from wild type parasites. Lanes 1 and 4 represent the detection of the full length wild type locus (PCR with p9-p8 and p31-p30 respectively); lanes 2 and 5 represent the detection of episomal DNA (PCR with p10 and p11); and lanes 3 and 6 represent the detection of integration of the insert (PCR with p9-p11 and p31-p11 respectively).
