Transmission electron micrographs of ultrathin cyrosections of P. falciparum intraerythrocytic schizont stages using PfNT1 antibodies. Immunogold labeling (15 nm gold particles) of PfNT1 antibodies bound to intraerythrocytic P. falciparum is depicted. Magnification is x 12,000 in panel A and x 50,000 in panel B. MC, Maurer’s clefts; N, nucleus; R, rhoptry; TVM, tubovesicular membrane; RBCM, red blood cell membrane; PVM, parasitophorous vacuole; PPM, parasite plasma membrane.
