Figure 1

Representative data obtained from MALDI-TOF-MS imaging for three cancer samples. Cancer samples #1, #4, and #5 correspond to papillary cancer samples #1, #4, and #5 in Figure 3. First column: photomicrograph of a tumor section with hematoxylin/eosin (H/E) staining. Second, third, and fourth columns: MALDI-TOF-MS profile with detection of BRAF/RAS mutations. X-axis indicates mass-to-charge ratio (m/z) to distinguish wild-type and mutant allele, and Y-axis indicates signal intensity.
