Fig. 6From: Conjugative type IVb pilus recognizes lipopolysaccharide of recipient cells to initiate PAPI-1 pathogenicity island transfer in Pseudomonas aeruginosa Binding of GST-pilV2’ to various LPS preparations in an enzyme-linked immunosorbent assay. LPS from Salmonella enterica and sample without LPS used as negative control. LPS derived from PAO1 carrying PAPI-1 showed the loss of binding capacity to GST-pilV2’. Results were presented as mean ± SD for three independent experiments. Statistical significance was assessed by One-way ANOVA (*** p < 0.001; ns: no significance, P > 0.05)Back to article page
