FIG. 2.

Effect of proteinase K and the recombinant form of the ligand binding domain of FnBPB from Streptococcus dysgalactiae on adherence to purified human fibronectin in vitro. Adherence of S. schleiferi NCTC 12218 and S. aureus 8325-4 was evaluated in the presence of 10 μg of the recombinant form of the ligand-binding domain of FnBP encoded by fnbB of Streptococcus dysgalactiae per ml and following treatment with proteinase K. Each isolate was tested in quadruplicate in an individual assay, and each experiment was performed in triplicate. Values are means ± SEM.
