Figure 5From: Vesicle-independent extracellular release of a proinflammatory outer membrane lipoprotein in free-soluble formLPS released by A. actinomycetemcomitans cells using a cell culture insert model. Filtrates from serum incubation at 0, 2, and 8 h (Panel A) and broth culture at 0 and 24 h (Panel B) were subjected to quantification of LPS by Limulus assay. The results are means (SD) from two independent experiments.Back to article page
