PF3D7_1134100 protein disulfide isomerase, putative

Upper panel: PfJ2 is an essential, ER-resident protein. A) PfJ2apt parasites were fixed with paraformaldehyde and glutaraldehyde and stained with DAPI (blue) and with antibodies against HA (green) and the ER-marker PfPMV (red). Ring (R), Trophozoite (T), and Schizont (S) stage parasites are shown. Z-stack Images were deconvoluted and shown as a single, maximum intensity projection. Scale bar represents 5 μm. Lower panel: PfPDI8 and PfPDI11 are redox-active ER proteins. PfJ2apt-PDI8glmS and PfJ2apt-PDI11glmS parasites were fixed with paraformaldehyde and glutaraldehyde and stained with DAPI (blue) and with antibodies against HA (green) and V5 (red). Ring (R), Trophozoite (T), and Schizont (S) stage parasites are shown. Z-stack Images were deconvoluted and shown as a single, maximum intensity projection. Scale bar represents 5 μm.
