Degradation of Spa by Esp. (A) Degradation of Spa in the biofilm matrix and cell wall-anchored fractions from Esp^WT-treated biofilms of S. aureus MR23 were examined by Western blotting. (B) Purified Spa was degraded by Esp^WT in vitro. Molecular sizes are given at the left. (C) Band intensities on the gel (B) were estimated using ImageQuant. Data points represent the means and standard deviations of results from three independent experiments. The standard deviation is less than the size of the symbol if no error bars are seen.
