Coimmunofluorescence assay of three plasmodial exoribonucleases and a core exosome member, PfRrp45, in ring-stage wild-type 3D7 parasites. The rabbit anti-PfRrp45, anti-PfRNase II, anti-PfRrp6 and mouse anti-PfDis3 antibodies were used in these assays. DAPI, 49,6-diamidino-2-phenylindole. Scale bar, 1 mm. Immunofluorescence assay (IFA) analysis revealed that PfRrp6 and PfRNase II localize as distinct foci at the nuclear periphery and that PfDis3 is localized in the cytoplasm adjacent to the nucleus at the ring stage .
