Localization of VTN and P47 domain/SERA5. (a) (i) Representative immunofluorescence assay (IFA) images of merozoites and schizont. (ii) Upper panels, Representative IFA images of schizont. VTN was probed with an isotype control mAb instead of anti-VTN mAb. Lower panels, Representative IFA images of schizont cultured in AlbuMAX-I medium. Target proteins were probed with anti-VTN mAb (green), anti-SE36 rabbit serum (red), and DAPI nuclear stain (blue). Scale bar, 5 μm. (b) Representative IFA images of merozoite and schizont stages under deconvolution microscopy. Probes used were the same as in panel a. Upper panels show the localization of P47 domain/SERA5 during merozoite and schizont stages. Lower panels show the intensity of green and red signals at the section of the gray line in the upper panel. Scale bar, 1 μm. (c) Western blotting of NHS, red blood cell (RBC) lysate, and iRBC lysate. The blots were probed with anti-SE36 mouse serum (diluted 1:1000), anti-VTN pAb (diluted 1:2000), anti-albumin pAb (diluted 1:2000), and anti-band 3 mAb (diluted 1:2000). Band 3 is RBC-specific protein and used as loading control. (d) Representative IFA images of early trophozoite and trophozoite. Target proteins were probed with anti-VTN mAb (green), anti-SE36 rabbit serum (red), and DAPI nuclear stain (blue). Scale bar, 5 μm.
