Comparative proteome analysis of untreated and Helicobacter pylori-treated HepG2

Figure 1 2-DE maps of untreated (A) and H pylori-treated HepG2 (B) cell proteins. The proteins from cells were extracted and separated on a pH 3-10 IPG strip, followed by a 12.5% SDS-polyacrylamide gel and silver staining. Spots that were found to be overexpressed have been annotated.

Figure 2 Peptide mass fingerprinting of the spot 10. The spot was in-gel digested with trypsin. After desalting, the peptide mixture was analyzed by MALDI-TOF-MS.
