FIG. 1.
Bam35 adsorption characteristics. (A) Efficiency of Bam35 adsorption to HER1410 (closed circles) and 4D22 (open circles) cells at different cell densities (MOI ∼10−4). The bars represent standard errors (of at least three experiments). The closed triangles and open triangles show HER1410 and 4D22 growth curves, respectively. (B) Kinetics of Bam35 adsorption to B. thuringiensis strains HER1410 (closed circles), 4D22 (open circles), 4I1 (closed triangles), 4Q2 (open triangles), and HER1410_R19 (closed squares). The inset depicts the kinetics of Bam35 adsorption to HER1410 during the first minute of infection. (C) Receptor saturation by Bam35 particles on HER1410 (closed circles) and 4D22 (open circles) cells. The experiments were performed as described in Materials and Methods.
