Selection of proteins overexpressed at all 3 lymphoma localizations. A selection of proteins that were consistently found up-regulated at nodal and extranodal lymphoma localizations is shown. Protein abundances in 5 lymphoma samples are displayed for each organ/lymphoma pair with a color code related to the corresponding DeepQuanTR score (maximum = e6-fold up-regulation; minimum =e6-fold down-regulation). Proteins up-regulated in comparison to the average protein expression in the corresponding normal host organ are displayed in green, down-regulated proteins in red. Proteins are sorted in descending order according to the average regulation score calculated from all 3 localizations. Antigens selected for further investigation are marked in bold.
