GSM5396971: Erlotinib treated sample 2; Homo sapiens; RNA-Seq
Total RNA was extracted using the Qiagen Rneasy Mini kit, following manufacturers instructions After the QC procedures, mRNA was enriched using oligo(dT) beads. First, the mRNA was fragmented randomly by adding fragmentation buffer, then the cDNA was 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 were 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 was completed through size selection and PCR enrichment.
