Northern blots verify the presence of F. tularensis sRNAs. RNA extracted from F. tularensis LVS (1) or mutant (2) bacteria in exponential phase was analyzed by Northern blotting using 32P-labeled oligonucleotides as probes (ProbeA specific for FtrA and ProbeB specific for FrtB). Approximate sizes are indicated based on RNA Marker and location of dyes in the gel.
