title: GSM3611668: E. coli K-12 MG1655_R3 [MG_3]; Escherichia coli K-12; RNA-Seq
library_construction_protocol: Total RNA was extracted using the Trizol reagent (Thermo Fisher Scientific) and the concentration and purity of the samples were determined using Nano Drop. RNA integrity was monitored using the R6K ScreenTape system on the Agilent 2200 TapeStation. gDNA was removed by Turbo DNase (Thermo Fisher Scientific) in the presence of RiboLock RNase Inhibitor (Thermo Fisher Scientific) for 60 min at 37°C. Following organic extraction (1x 25:24:1 v/v phenol/chloroform/ isoamyalcohol, 1x chloroform), RNA was recovered by overnight precipitation with 3 volumes of 30:1 100 % ethanol/3 M sodium acetate (pH 5.2). The RNA preparations were further treated with RiboZero (Illumina) and the concentration of the samples was determined with Qubit. cDNA libraries for the Illumina sequencing platform were constructed using NEBNext Ultra Directional RNA Library Kit following the manufacturer's instructions.
