IL-12 p70 production by DC 48 h after a bacterial pulse^a

Stimulus	IL-12 p70 production (pg/ml)
	Wild type	phoP	phoPc
Bacteria	154 ± 6	164 ± 16	188 ± 6
LPS	115 ± 7	103 ± 5	106 ± 7

^aSee the legend to Fig. 7 for details of the incubation conditions. IL-12 p70 production in medium alone was 90 ± 5 pg/ml. The values shown are determined from a standard curve run in parallel and represent the means ± 1 standard deviation of triplicate supernatant aliquots from a single well infected with the indicated bacterial strain or stimulated with purified LPS from the indicated bacterial strain. The data are representative of three independent experiments.
