Proteins observed by peptide mass spectrometry from uninvolved and psoriatic skin of a single patient. For each protein the number of unique peptides and the total peptide count, which includes multiple observations of the same peptide, are listed. The peptide count has been divided by the molecular weight and proteins are listed in order of the resulting product. All 13 proteins identified from the uninvolved skin of this individual are listed together with the first 13 (of 66 total) proteins seen in psoriatic skin.
