title: GSM2349923: Flask state 1 (IPTG-/aTc-/Ara-); Escherichia coli; RNA-Seq
library_construction_protocol: Cultures were spun down at 4 °C, 15,000 × g for 3 minutes. Supernatants were discarded after centrifugation and cell pellets were flash frozen in liquid nitrogen for storage at -80 °C. Cells were lysed with 1 mg of lysozme (Sigma Aldrich L6871) in 10 mM Tris-HCl (pH 8.0) (USB 75825) supplemented with 0.1 mM EDTA (USB 15694). RNA was extracted with PureLink RNA Mini Kit (Life Technologies) and further purified and concentrated with RNA Clean & Concentrator-5 (Zymo Research) to assure sample quality. The purified RNA samples were analyzed using a Bioanalyzer (Agilent) and Ribo-Zero rRNA Removal Kit for bacteria (Illumina) was used to deplete rRNA from the samples. Strand specific RNAtag-seq libraries were created by the Broad Technology Labs specialized service facility (SSF) using the standard protocol described in Shishkin et al. Nature Methods 2016.
