Ex vivo activation of peripheral blood mononuclear cells:

…For the activation of monocytes, 200 l PBMC were stimulated in separate wells (ninety-six-well plates) with 10 g/l of ultra-pure lipopolysaccharide (LPS; List Biological Laboratories, Inc.) or an equal volume of sterile endotoxin-free water as a negative control. PBMC were incubated at 37C in 5 % CO₂ and supernatants were removed after 24, 48 and 72 h for the analysis of monocyte cytokine production as described below.
