Fig. 1. 2-DGE of cellular proteins from S. aureus 8325. (a) Proteins separated using IPG pH 4–7 and (b) IPG pH 6–11 two-dimensional gels. Numbers refer to identifications shown in supplementary data (http://mic.sgmjournals.org). Boxes show the positions of spots only found in strain COL. Broken boxes show the positions of spots found only in cells following their growth in the presence of TX-100. NI, not identified; D suffix, potential dimer; F suffix, protein spot corresponds to a fragment of a larger translated ORF.
