Human immune sera recognizes 3D7 and PfHsp70x-KO parasites. Synchronized 3D7 and PfHsp70x-KO parasites were incubated with either pooled human sera from Kenya where malaria is endemic (top panels) or pooled nonimmune human serum from the United States (bottom panels). Recognition by the serum was determined using a PE-conjugated anti-human IgG antibody and flow cytometry. Uninfected red blood cells (uRBC) were also assayed. Side scatter is shown on the y axes, and PE fluorescence is shown on the x axes.
