Figure 4From: Improving Detection Accuracy of Lung Cancer Serum Proteomic Profiling via Two-Stage Training Process The splitting peaks in two-stage training protocol and the density peaks of these two proteins in all sera samples. (A) The first splitting peak from the first-stage training set marker showing a protein peak marker of 11480 Da on the CM10 chip (vertical line). Protein mass spectra were shown in sera of individuals with lung cancer (left), healthy control (middle), and inflammatory disease (right). (B) The first splitting peak of the second-stage training set marker showing a protein peak of 12580 Da (vertical line). (C) Density peak of 11480 Da protein in the sera of all samples. (D) Density peak of 12580 Da protein in the sera of all samples.Back to article page
