Titer of autoantibodies to the panel of 13 TAAs in ovarian cancer and normal individuals. The range of antibody titers to each of the 13 TAAs is expressed as optical density (OD) obtained from ELISA. The high titer reactivity of some ovarian cancer sera and the distinct difference between cancer and normal individuals are demonstrated. Y-axis, OD values. X-axis, the panel of 13 TAAs. 1, survivin; 2, p53; 3, p16; 4, cyclin B1; 5, cyclin D1; 6, cyclin E; 7, cyclin E; 8, Koc; 9, Imp1; 10, p62; 11, CDK2; 12, p90; 13, c-Myc.
