Figure 5. Up-regulation of specific outer membrane protein (OMP) in CSE-exposed P. gingivalis.

Figure 5

Outer membrane proteins of P. gingivalis grown in GAM and GAM-CSE were isolated by differential extraction with Triton X-100. 20μg total OMP extracts were run through a 4-15% gradient gel. MALDI-MS of excised bands followed by comparison with the ORF database of P. gingivalis W83 from The J. Craig Venter Institute identified the major CSE up-regulated bands, as shown.
