FIG. 6.
Northern blot analysis of sarA, RNAIII, ssp, scp, and aur in the protease-negative clinical S. aureus strains and their corresponding sarA mutants. 16S rRNA was used as an internal control of the amount of total RNA loaded. The same filter was hybridized with each of the specific probes. KS33 and its sarA mutant were on a separate membrane.
