Half-lives of the ompA and lpp mRNAs as the average of two determinations by Northern blotting and subsequent quantification by PhosphorImaging. The relative changes in half-lives are shown as fold regulation. The wild-type strain MC4100 and the mutant strains are described in Materials and Methods.
