PEBP1 detection in ascites cells, normal and tumor tissues, and tumor cell lines. Cell lysates from normal tissues [ovary (a2), testis (a3)], tumor tissues [ovary (a4), prostate (a5), testis (a6), cervix (a7), uterus (a8)], ovarian cancer ascites cells (a9–14), prostate tumor cell lines (b1: BPM1; b2: RWPE-1; b3 VCap; b4: DU145) and ovarian tumor cell lines (c1: A1847; c2: A2780; a3: CaOv3; a4: ES2; a5: Hey; a6: IGROV1; a7: OvCar3; a8: OvCa5; a9: OvCar10; a10: Ov-90; a11: PEO-1) were diluted in PBS and separated by electrophoresis. After blotting, membranes were hybridized with anti-PEBP1 pAb. The signal was detected with HRP-labeled anti-rabbit Ig. As control of antibody specificity, lane a1 was loaded with a recombinant PEBP1 antigen fused to GST (49 kDa) (Abnova Corporation, Taipei City, Taiwan).
