RNA extraction and RNA-sequencing method for transcriptomic analysis of <i>Mycobacterium tuberculosis</i>

phase separation, and column-based purification to produce high yields of pure, intact RNA followed by rRNA depletion and cDNA library preparation. The detection of unique transcripts was optimized at a sequencing depth of 15 million reads. This method detected differential RNA expression in experimental sets with and without pyrazinamide exposure, demonstrating that the method is suitable for RNA-seq applications.
