Figure 2. Binding of CD11 to C. difficile cell wall under different nutrient conditions.
(a) Binding of CD11 to intact cell wall in live C. difficile cells. (b) Binding of CD11 to isolated cell wall materials. Abbreviations: PBS, phosphate buffered saline; M, growth medium; BHI, brain heart infusion; YE, yeast extract; P, peptone; P3, peptone No. 3; D, dextrose; C, L-cysteine; B, bound fraction (pellet); U, unbound fraction (supernatant); W, wash, loosely bound fraction; L, molecular weight ladder. The arrows indicate the band of CD11.
