Influence of the age of sheep red blood cells on virus-induced and hypotonic hemolysis.

abstract：:The stimulatory effect of lipopolysaccharide (LPS) on human macrophages was found to be neutralized by the detergent octylglucoside (OG). Both macrophage stimulation and reactivity in a limulus amebocyte lysate test were suppressed by suspension of LPS in OG at concentrations between 0.25 and 2.5 mM, whereas other sti...
