SDS-PAGE and western blot analysis of PvAARP and PkAARP. (a) Crude recombinant proteins of full-length PvAARP and PkAARP [rPvAARP-FL and rPkAARP-FL] were expressed with the WGCF expression system. (b) Recombinant PvAARP-N [Pv, 0.5 µg] and PkAARP-N [Pk, 0.5 µg] proteins were expressed in E. coli and purified to a single band [arrowhead]. (c) Specific band have been detected with anti-glutathione S-transferase antibody [Gst], mouse serum [M] and rabbit immunized [R] with PvAARP-N or PkAARP-N. (d) P. knowlesi A1-H.1 parasite lysate was recognized with anti-PvAARP-N [α-Pv] and anti-PkAARP-N [α-Pk] antibody, nor non-immunized rabbit (α-NI). The full length of SDS-PAGE and western blots are presented in the Supplementary Fig. S2. (e) Immunofluorescence assay of anti-PvAARP-N and PkAARP-N with P. knowlesi A1-H.1. pRBC, parasitized-red blood cells; uRBC, uninfected-red blood cells; DAPI, 4’,6-diaminidino-2-phenylindole. Bars indicate 5 μm.
