Ribosomal Proteins. Upper part: Quantitation profiles of the unique peptides assigned to the ribosomal protein RS30 detected in the first experiment. Labels are representing the samples: 114 - NZO_SD; 115 - SJL_HF; 116 - SJL_SD and 117 - NZO_HF. Colors orange and blue correspond to clusters 1 and 4 the peptides were identified in. Lower part: Protein sequence with positions of mapped peptides. Vertical bars displayed on the x-axis indicate predicted trypsin cleavage sites. The non-tryptic peptide was found with X!Tandem option 'refine unanticipated cleavages'.
