a. The biofilm of S. epidermidis RP62A and Aap were stained by SYTO9 and Cy3, respectively. After obtaining the fluorescence photomicrographs under a CLSM (Figure 7), the fluorescence quantities of SYTO9-stained cells, Cy3-stained Aap were determined using ImageJ program.
b. “SYTO9” stands for the fluorescence quantities of SYTO9-stained cells.
c. “Cy3” stands for the fluorescence quantities of Cy3-stained Aap.
d. “Cy3/SYTO9” represents the proportion of Aap in the biofilms.
e. Fluorescence quantities of SYTO9 and Cy3 in biofilm co-cultured with MAb18B6 were obtained from other images (not shown) which captured at the area away from the boundaries of the crater-like micropores where Cy3-stained Aap was up-regulated in all Z-positions.
