Expression of FPPS protein during the three stages of the intra-erythrocytic cycle of Plasmodium falciparum using parasites transfected. α-HA (antibody against the epitope of haemagglutinin protein (HA), encoded fused to the protein of interest-FPPS). Controls for the synchronization of intra-erythrocytic stages of the parasite: α-pTEX150 (antibody against pTEX150, protein constitutively present during the intra-erythrocytic cycle of the parasite), α MSP2 (antibody against MSP2, protein present only in the schizont stage). (R) ring trophozoite (T) trophozoite, (S) schizont. Molecular size standards are indicated on the left (kDa).
