SERA6 is a soluble parasitophorous vacuole (PV) protein which may partially interact with the PVM. Upper panel: IFA demonstrates colocalization of the anti-SERA6 and anti-SERA5 signal in mature schizonts, except that the SERA6 signal additionally shows an association with the outer confines of the intracellular parasite, probably corresponding to the PVM. Scale bar, 5 μm. Lower panel: Immuno-electron microscopic localization of SERA6 in a P. falciparum schizont, using the anti-S6C1 antibodies labelled with 10 nm immunogold. The majority of the signal is clearly associated with the peripheral space between intracellular merozoites, consistent with a PV localization. Magnification, x 15000.
