Proteins showing different abundances in plasma samples of patients with intermediate and high-risk PE compared with individuals presenting with low-risk PE, detected by nontargeted 2D-DIGE.

<p>Pos: Position numbers correspond to the position of the proteins in the gel image (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0100902#pone-0100902-g001" target="_blank">Figure 1</a>).</p><p>MW/pI: Theoretical molecular weight (MW) in kDa and theoretical pI.</p><p>PMF: peptide mass fingerprinting.</p><p>NP: Number of peptide mass values matched from MASCOT PMF.</p><p>SC: Amino acid sequence coverage for the identified proteins.</p><p>Sco: MASCOT MS protein score, obtained from MALDI-TOF/TOF spectra from the top hit and the second one. Larger differences indicate a better result.</p><p>FP: Number of fragmented peptide masses by tandem mass spectrometry.</p><p>Expect: Quality of an individual match. It is the number of times in the search we could expect to get a match with this score or higher by chance.
