(A) Mass spectrometric data were searched against HuDB, HBDB and HFDB databases, and then arginine, lysine, and proline residues in all PSMs were counted and classified into isotope-labeled (red) and unlabeled (blue) residues. (B) Pie-charts showing the number of proteins classified as human and bovine. Labeled: identification from all labeled peptides; partially labeled: identification from both labeled and unlabeled peptides; non-labeled: identification from unlabeled peptides only.
