Figure 3From: The inflammatory cytokine tumor necrosis factor modulates the expression of Salmonella typhimurium effector proteinsSipA and AvrA protein expression. (A) Western blot assay for the expression of SipA and AvrA. (B) Relative protein band intensity in Ponceau S Red staining. Data are reported as representative results from three independent experiments. (C) The relative intensity of the Western blot bands. The data are reported as the mean ± SD of three independent experiments. *P < 0.05 was considered significant.Back to article page
