Fig. 7. IL-6 inhibition experiments. MonoMac 6 cells (A) and ECV-304 cells (B) were pre-incubated with MY4, anti-hsp70 or anti-hsp90 polyclonal sera, or a combination of these antibodies prior to stimulation with 1 ng ml^-1 of native LPS, in 5% HPS. Control experiments with irrelevant polyclonal sera were also performed. The biological activity of LPS was tested by measuring induction of IL-6 using an ELISA. Each data point represents several independent experiments.
