Figure 4From: Lipopolysaccharide induces nitric oxide synthase expression and platelet-activating factor increases nitric oxide production in human fetal membranes in cultureInduction of iNOS mRNA expression in human fetal membranes (FM), cultured without serum, following treatment with LPS (1 μg/ml) alone or in combination with sodium butyrate (SB) (2 mM). Lane 1 FM control; lane 2 FM + LPS; lane 3 FM LPS + SB; lane 4 CHOiNOS positive control; lane 5 iNOS short standard; lane 6 PCR blank (no template); lane M ΦX174 DNA/Hae III Marker (Promega). Lanes 2–4 show characteristic iNOS bands at 310 base pairs (bp). One example is shown of four similar results with four different samples of fetal membranesBack to article page
