Fig 4. The effect of sarA and sarS on tst and TSST-1 toxin expression in RN4282.

Fig 4

A and C. Quantitative qRT-PCR measurements of tst expression in the indicated strains, setting RN4282 as 100%. Bars show +/- standard deviations. All data were compiled from three independent experiments. Statistical significance was evaluated by Student’s paired t test, and data were considered significant when P was <0.05. B and D. Western blot of TSST-1, using anti-TSST-1 polyclonal antibody after precipitation from OD-normalized supernatants of the indicated strains (Materials and Methods). The experiment shown is representative of several independent experiments.
