Abstract
The stimulatory effect of lipopolysaccharide (LPS) on human macrophages was found to be neutralized by the detergent octylglucoside (OG). Both macroph age stimulation and reactivity in a limulus amebocyte lysate test were supp ressed by suspension of LPS in OG at concentrations between 0.25 and 2.5 mM , whereas other stimulatory lipopeptides and lipid containing stimulants we re unaffected by OG. LPS at concentrations causing maximal stimulation of m acrophages could be completely neutralized by non-toxic concentrations of O G. In addition, it was found that the neutralization in complex mixtures of macromolecules, such as bacterial cell lysate, was specific for LPS and th at the stimulatory activity of the other substances in the mixture was not affected by the OG.
