Proteomic variation and diversity in clinical Streptococcus pneumoniae isolates from invasive and non-invasive sites
Fig 5
A heat map representation of the 40 protein spots identified by LC-MS.
The identified protein spots showing conserved and differential abundance levels between the invasive and non-invasive site isolates were plotted on the heat map using the normalised spot volumes of the replicate gels of each isolate in the invasive and non-invasive group. The gene locus numbers are based on the publicly available S. pneumoniae TIGR4 genome annotation.
