PF3D7_0731500 erythrocyte binding antigen-175

Localization of falcipain 1 (FP1) in merozoites by immunofluorescence imaging. Samples of merozoites were smeared and fixed in 1% paraformaldehyde. The slides were incubated with an antibody to falcipain 1 or with antibodies specific to the rhoptry (RopH2) and microneme (EBA-175) proteins. Nuclei were stained with 4’,6-diamidino-2-phenylindole (DAPI). The lack of colocalization indicates that falcipain 1 is found in compartments at the apical end of the merozoite that are distinct from the rhoptries and micronemes.
