title: GSM8801001: AA_H_5; Homo sapiens; RNA-Seq
library_construction_protocol: Total RNA was extracted from tissues using TRIzol (Invitrogen, Carlsbad, California, USA) according to manual instruction. Total RNA was processed using mRNA enrichment. The mRNA was enriched using magnetic beads with Oligo(dT) to capture mRNA with a polyA tail. The obtained RNA was fragmented using a breaking buffer, and random N6 primers were used for reverse transcription.Subsequently, double-stranded cDNA was synthesized. The ends of the synthesized double-stranded DNA were blunted and 5' end-phosphorylated. A single-base overhang "A" was added to the 3' end, and a bubble-shaped adapter with a protruding "T" at the 3' end was ligated. The ligated products were PCR-amplified using specific primers. The PCR products were denatured to form single-stranded DNA, and single-stranded circular DNA libraries were generated using a bridged primer. The constructed libraries underwent quality control, and after passing, they were subjected to sequencing.
