MALDI TOF/TOF MS analysis of differentially expressed protein. (A) GST pi 2 is identified with MALDI TOF/TOF MS according to the matched peaks. MS signals were derived from the parent ion at m/z 1351.81, for which the amino acid sequence, PPYTIVYFPVR, was deduced based upon these b‐ions and y‐ions in MALDI‐TOF/TOF MS. (B) Protein sequence of GST pi 2 is shown and matched peptides are underlined. (C) GST A5 is identified with MALDI TOF/TOF MS according to the matched peaks. MS signals were derived from the parent ion at m/z 1245.7, for which the amino acid sequence, SHGQDYLVGNR, was deduced based upon these b‐ions and y‐ions in MALDI‐TOF/TOF MS. (D) Protein sequence of GST A5 is shown and matched peptides are underlined.
