title: GSM3733434: Tumor_S33Y_s2160; Mus musculus; RNA-Seq
library_construction_protocol: RNA purification from five representative tumors of each group was performed using Qiagen RNAeasy columns (Qiagen, Inc., Valencia, CA) followed by DNase digestion. Sample integrity was measured using an Agilent 2100 Bioanalyzer (Agilent Technologies, Foster City, CA).  All samples had RIN values of 8.5-10 prior to any further processing. After the QC procedures, mRNA from eukaryotic organisms is enriched using oligo(dT) beads. For prokaryotic organisms or eukaryotic organisms' long-non-coding libraries, rRNA is removed using the Ribo-Zero kit that leaves the mRNA. First, the mRNA is fragmented randomly by adding fragmentation buffer, then the cDNA is synthesized by using mRNA template and random hexamers primer, after which a custom second-strand synthesis buffer (Illumina) , dNTPs, RNase H and DNA polymerase I are added to initiate the second-strand synthesis. Second, after a series of terminal repair, A ligation and sequencing adaptor ligation, the double-stranded cDNA library is completed through size selection and PCR enrichment.
