Figure 1

A pseudocolor difference gel electrophoresis (DIGE) image from a representative subject (subject 19). Proteins from the saline treated lung lobe were conjugated to Cy3 (shown in green) and protein from the LPS treated lobe was conjugated to Cy5 (shown in red). Equal amounts of protein were loaded onto the gel from each condition. Green spots represent proteins that were relatively higher in the saline treated lobe; red spots indicate proteins that were relatively higher in LPS treated lobe; yellow spots represent proteins that were expressed at relatively similar levels. Each of the circled spots was identified by mass spectrometry and labeled according to identification as follows: haptoglobin (HP), surfactant protein A (SPA): immunoglobulin J chain (IgJ), α1-antitrypsin (AAT), fibrinogen-γ (Fγ), α2-HS-glycoprotein (αHSG), immunoglobulin G (IgG).
