Figure 1 Identification of quantitatively dysregulated expression of S100A4. A: Quantification of S100A4 through the isotopically labeled fragment ion signals of the peptide “TDEAAFQK”. The areas under the monoisotopic peaks represent the relative abundance of peptides, light [lymph node metastasis (LNM)]/heavy (non-LNM) = 3.04:1; B: Identification of the peptide “TDEAAFQK” from S100A4 by MS/MS.
