Figure 1: Example of FFPE tryptic peptide digest of a human ovarian teratoma. Panels A-F show the sample at low magnification (scale bar in F = 2mm). Panel A is the post-measurement H&E stained sample, panels B-E show four different peptides, panel F is a merge of panels B-E. Panels G-I show the area indicated by the dotted box in panel A, scale bar in I = 100 µm. For full figure legend, please view Ly et al. Used with permission.
An example analysis aimed at discriminating melanoma and benign nevus using MALDI imaging, reused with permission from Al-Rohil et al. Panels A and C provide a macroscopic overview of the tissue sections, with B and D highlighting specific regions of interest (i.e., melanoma and nevus, respectively). Panels E and F depict the average mass spectra per tissue type. Used with permission.
