Detection of pancreatic cancer with normal carbohydrate antigen 19-9 using protein chip technology

Figure 1 Spectral expression of the four proteins in Pattern 1. The spectra of the selected biomarkers (A: 5870.0549 Da; B: 6468.2454 Da; C: 7777.958 Da; D: 4291.7922 Da) in the pattern distinguishing pancreatic cancer from healthy individuals. The healthy individuals are group 0 and the cancer patients are group 1.

Figure 2 Spectral expression of the six proteins in Pattern 2. The spectra of the selected biomarkers (A: 4122.6162 Da; B: 3964.2531 Da; C: 8920.0244 Da; D: 6683.7967 Da; E: 4163.9423 Da; F: 4144.4237 Da) in the pattern distinguishing pancreatic cancer from benign disease. Patients with benign disease are group 0 and the cancer patients are group 1.
