CPCA-W scores plots of the strain-blocked GC–MS metabolic profiles data. The scores plots for each of the strain-blocked data are presented on a–c plots, where samples taken at separate time points are presented by different coloured circles. The dashed arrows display the direction of the separation according to incubation time. Different letters on each plot indicate the S. lividans strains; wild (W), empty plasmid (E), and mTNF-producing (T)
