(D, Top) Immunofluorescence micrographs show rabbit a-PfPMV antibodies (Ra-PfPMV, green) label PfPMV in the ER. Colocalizations were performed with mouse a-PfPMV antibodies (Ma-PfPMV, red), shown previously to label PMV in the ER . (Middle) a-HA antibodies (red) label PfPMVHA (Top) and PvPMVHA (Bottom). P. vivax) in the parasite ER. (Bottom) a-HA antibodies (red) label PvPMVHA in the ER, as shown by clocalization with ERC (green). A strong perinuclear signal was observed in parasites expressing PvPMVHA or PfPMVHA (middle panels, red). Both proteins colocalized with rabbit anti-PfPMV antibodies, indicating the location was the ER. PvPMVHA also colocalized with ERC (bottom), as shown previously for PfPMVHA.
