GSM3334100: RNA_S1; Streptomyces avermitilis; RNA-Seq
Harvested cells were washed with polysome buffer (20 mM Tris-HCl pH 7.5, 140 mM NaCl, 5 mM MgCl2), and then resuspended with lysis buffer (0.3 M sodium acetate pH 5.2, 10 mM EDTA, 1% Triton X-100). The cell suspension was then frozen with liquid nitrogen, and lysed by grinding using mortar and pestle. The cell lysate was centrifuged at 4 oC for 10 minutes at 16,000 g and the supernatant was stored at -80 oC until used for RNA extraction. RNA was extracted by mixing with equal volume of phenol:chloroform:isoamyl alcohol = 25:24:1 solution. The mixture was then centrifuged and upper aqueous phase was recovered. The RNA was purified with ethanol precipitation. The purified RNA was treated with DNase I (New England Biolabs) to remove any genomic DNA contamination. Ribosomal RNA was depleted with Ribo-Zero rRNA Removal Kit Bacteria (Epicentre) according to the manufacturer's instructions. The RNA-Seq libraries (Sample 7 to 14) were constructed using TruSeq Stranded mRNA Library Prep Kit (Illumina) based on manufacturer's instructions.
