PF3D7_1346300 DNA/RNA-binding protein Alba 2

PfAlbas localize to perinuclear foci in ring stages and expand to the cytoplasm in mature forms. (A) Immunofluorescence analysis of PfAlba1, PfAlba2 and Pfalba4 distribution throughout the parasite life cycle (Rings, Trophozoites, Schizonts). The anti-PfAlba antibodies (Ab 74–2 for PfAlba1; Ab 233 for PfAlba2; Ab 237–2 for PfAlba4) were used at 5.5, 4.5 and 8 mg/ml, respectively. Anti-rabbit Alexa-488 secondary antibodies (Molecular Probes) were used at a dilution of 1:500. Scale bars represent 1 mm. (B) Immunofluorescence analysis of 3D7 Rings, Trophozoites and Schizonts stained with anti-PfAlba4 (red) and anti-PfSir2 (green) antibodies. Scale bar represents 1 mm.
