Fig. 3. Influence of Legionella LPSs on BMGs of LPS-responsive mice. BMGs
(5x105 cells) from C3H/HeOU mice were incubated for 24 hours
at 37°C with various concentrations of LPSs from B. pertussis
(), and from the L. pneumophila strains CS338 (
), RC1
(
), and 811 (
). CD14 was detected by incubation with the
anti-CD14 antibody rmC5-3 (2.5 µg/ml, 30 minutes, 0°C), and further
incubation (30 minutes, 0°C) with a FITC-labeled goat anti-rat Ig mAb. The
percentage of fluorescent cells was determined by FACS analysis of the gated
granulocyte population.
