title: GSM8754310: mouse extended totipotent stem cell rep1; Mus musculus; RNA-Seq
library_construction_protocol: Total RNA was isolated using the RNeasy Mini Kit RNA sequencing libraries were constructed by using magnetic beads with oligo (DT) enriched mRNA. After that, fragment buffer was added to break the mRNA into short segments. Using mRNA as template, a strand of cDNA was synthesized using six base random primers. Then buffer, dNTPs, DNA polymer I and RNase H were added to synthesize a two strand cDNAs, which were purified using AMPURE XP beads. The purified double stranded cDNAs were repaired, a-tailed and sequenced, and then the fragment size was selected by AMPURE XP beads. Finally, PCR amplification was carried out and PCR products were purified with AMPURE XP beads to obtain the final library. The fragmented and randomly primed 2 × 100- bp paired-end libraries were sequenced using an Illumina HiSeq 2500.
