LC–MS/MS analysis of the proteomes of normal duct and PANC-1 cells. (A) Total of 1547, 1554, and 1569 proteins with 1% FDR were identified from iteration 1, 2, and 3, respectively, in the sample of normal duct cells. Among the identified proteins, 91, 79, and 100 were found only in iteration 1, 2, and 3, respectively, but not in the other two iterations; dozens were found in two iterations but not in the other one; 1382 were commonly found in all three iterations. In parallel, a total of 1666, 1642, and 1660 proteins with 1% FDR were identified from iteration 1, 2, and 3, respectively, in the sample of PANC-1. Among the identified proteins, 113, 96, and 124 were found only in iteration 1, 2, and 3, respectively, but not in the other two iterations; dozens were found in two iterations but not in the other one; 1407 were commonly found in all three iterations. (B) Total of 1547, 1679, and 1779 proteins were identified from the first iteration, combined first and second iterations, and combined three iterations, respectively, in the sample of normal duct cell; a total of 1666, 1823, and 1947 proteins were identified from the first iteration, combined first and second iterations, and combined three iterations, respectively, in the sample of PANC-1 cells.
