Immunoelectron microscopy of saponin permeabilized IE to confirm PfMC-2TM presence at the erythrocyte membrane. a, b A preembedding staining protocol was applied to analyse PfMC-2TM membrane association by immunoelectron microscopy. Trophozoite IE were permeabilized with saponin and incubated with the immune serum rabbit α-PfMC-2TM-CT (I) or the respective pre-immune serum (PI). Recognized proteins are visualized with 10 nm gold particles. Different sections are shown depicting PfMC-2TM association with the erythrocyte membrane (a) and with Maurer’s clefts (b).
