The efficiency of Met-peptide enrichment from A431 cells under the three different PDT conditions. The numbers of Met- and non-Met-peptides detected in the non-enriched and enriched samples were calculated for each condition. The three conditions (with swapping experiments) were analyzed separately. The red bars indicate the Met-peptides specifically identified in either non-enriched or enriched samples, while the purple bars indicate Met-peptides that were commonly identified in both, and the blue and green bars represent non-Met-peptides. The number above each column denotes the Met-peptides as a percentage of the total identified peptides.
