Figure 3From: Identification of potential serum peptide biomarkers of biliary tract cancer using MALDI MS profiling Average spectra, gel and 3D spectral views for two significant peaks discriminating BTC (red) and healthy control (green) samples. A. The peak at m/z 2212.3 was generally of lower intensity in BTC samples compared to healthy samples. B. The peak at m/z 5805.0 was generally of higher intensity in BTC samples compared to healthy samples.Back to article page
