FIG. 3.

Cell death (necrosis and apoptosis) in B. anthracis infection as measured by enzyme-linked immunosorbent assay. Measurements of necrosis and apoptosis have been normalized in each case to measurements obtained from untreated cells, such that levels of cell death are expressed as the ratio of experimental to untreated cells. Data shown are from representative experiments, and each column is the average of at least three individual measurements. Error bars indicate the standard deviation of each data set.
