Identified H. pylori outer membrane proteins differentially expressed following DHA treatment.

§ Molecular weight in kDa and pI in parentheses. Spot Mascot legend depicted in figure 5B.* Proteins 17a and 17b were identified from the same spot in the 2D-electrophoresis gel. Mascot score is defined as −10*Log10 (P), where P is the absolute probability. Protein score confidence interval (C.I.) % rates the confidence level of the Mascot Score to a 5% significance level. The closer the C.I.% is to 100%, the more likely the protein is correctly identified.Twelve proteins identified by MALDI TOF/TOF mass spectrometry presented a differential expression level when comparing untreated control and DHA-treated bacteria. These proteins were mostly related with induction of stress condition.
