qRT-PCR comparison of transcription of selected S. aureus genes. Shown are the relative levels of transcripts of the asp23, crtN, and sigB genes from S. aureus strains COL, SKC31, SKC31(pBT2), and SKC31(pBCSA). Expression of each gene was normalized to the expression of the reference gene for 16S rRNA from each strain. Relative values of expression in the test strains were calculated and compared to that of parental strain COL. All values are averages (±standard deviation) from triplicate analyses that used three independent preparations of RNA.
