GSM2822966: E. coli hhahha2; Escherichia coli 042; RNA-Seq
Total RNA was isolated from the cell pellets using a bead mill and the mirVana RNA isolation kit (Ambion) including DNase treatment. From the total RNA samples, ribosomal RNA molecules were depleted using the Ribo-Zero rRNA Removal Kit for bacteria (Illumina). From the rRNA depleted RNA samples, first-strand cDNA was synthesized using a N6 randomized primer. After fragmentation, the Illumina TruSeq sequencing adapters were ligated in a strand specific manner to the 5' and 3' ends of the cDNA fragments. The cDNA was finally amplified with PCR (15 PCR cycles) using a proof reading enzyme. For Illumina sequencing, cDNA libraries were pooled in a 25:1 ratio. The library pool was fractionated in the size range of 250-500 bp using a differential clean- up with the Agencourt AMPure kit. The cDNA pool was sequenced on an Illumina NextSeq 500 system using 75 bp read length.
