Although gene expression studies have been performed on Escherichia coli using starvation models, there has been no study of long-term changes in gene expression due to the difficulty of isolating RNA of sufficient yield and quality at late time-points. Furthermore, there is evidence that these starvation models are not physiologically relevant compared to aging cells in batch culture. This document describes the development of a methodology for isolating RNA from aging and starving bacterial cells using organic extraction. Reverse-transcription quantitative PCR is then utilized to measure...
