GSM5412579: Wild-type RNA-Seq biological replicate 2; Saccharomyces cerevisiae; RNA-Seq
Cell pellets were washed once with sterile water and snap-frozen in liquid nitrogen. Together with fixed OD units of S. pombe cells as spike in, total RNA was extracted using the hot acid phenol protocol (acid phenol:chloroform:isoamyl alcohol 125:24:1) and TE-SDS buffer, then precipitated in ethanol with 0.3 M sodium acetate before re-suspension in DEPC-treated sterile water. Total RNA from yeast was incubated with rDNase (Machery-Nagel rDNase Set) and column purified (Machery-Nagel NucleoSpin RNA) prior to sequencing library preparation. Total RNA was used to generate strand-specific libraries for polyadenylated RNA sequencing using the TruSeq Stranded mRNA Library Prep Kit (Illumina RS-122-2101) according to the manufacturer's instructions. Library quality control was performed using the Agilent 2200 TapeStation with D1000 screentape (Agilent Technologies). Each library was sequenced on the HiSeq 2500 platform using V4 chemistry (Illumina) and typically generated ~55 million 101 bp strand-specific paired-end reads per sample.
