Figure 2From: Lipopolysaccharide enhances the cytotoxicity of 2-chloroethyl ethyl sulfideCell viability as a function of LPS and CEES concentration. CEES at concentrations greater that 300 μM were toxic (p < 0.05) to RAW 264.7 macrophages at LPS levels of 25 ng/ml or greater. Cell viability was measured, after 24 hours, by the MTT assay as described in the Methods.Back to article page
