Cellular proteome heterogeneity in the investigated S. aureus isolates. A Numbers of identified cellular proteins of the six investigated S. aureus isolates. B Principal component analysis (PCA) based on the LFQ intensities of identified cellular proteins. The PCA analysis was performed on the identified cellular proteins of all six S. aureus isolates. The PCA with averaged values is presented in Supplementary Figure S 6. Note that the small numbers above each data point refer to the respective replicate measurement. C Heat map based on the LFQ intensities of identified cellular proteins. The data for each strain are based on three independent replicates. The respective data are presented in Supplementary Table S 2
