mRNA was extracted from total RNA using magnetic beads with oligo-dT then were fragmented randomly. The first strand of cDNA and the second strand are then synthesized using reverse transcriptase. The reverse transcription product is subjected to terminal repair, followed by addition of an A base at the 3' end. Subsequently, the fragments were ligated with a Illumina universal adapter. After PCR amplified, the ligation products were purified in order to remove the incompletely ligated fragment and the self-ligated adapter.
