Expression profile of PfHsp70-x: (A) mRNA expression profile of PfHsp70-x during the 48 h asexual cycle from three different strains of P. falciparum (red: 3D7, blue: HB3 and yellow: DD2), adapted from PlasmoDB. (B) Western blot analysis of total parasite lysate at different stages of P. falciparum asexual cycle. Ring stage (2–8 hpi), Trophozoite stage (24–30 hpi) and Schizont stage (36–48 hpi); hpi: hours post-infection.
