GSM1239374: AA; Apostichopus japonicus; RNA-Seq
Total RNA from NA,DA and AA intestines was extracted and DNase-treated using RNeasy Mini Kit and RNase-Free DNase Set (Qiagen, Germany), following the manufacturer’ s instructions. The quality and concentration of RNA were measured by NanoDrop 1000 (Thermo) after which the mRNA in total RNA was enriched by using the oligo(dT) magnetic beads. After the addition of fragmentation buffer, the mRNA was interrupted and formed short fragments (~200 bp). The first strand cDNA was then synthesized by the random hexamer-primer, using the mRNA fragments as templates. Buffer, dNTPs, RNase H and DNA polymerase I were added to synthesize the second strand. The double strand cDNA was purified using the QiaQuick PCR extraction kit, and washed with EB buffer so as to facilitate end repair and the addition of a single nucleotide A (adenine). Finally, sequencing adaptors were ligated to the fragments. The required fragments were purified by means of agarose gel electrophoresis and enriched by PCR amplification.
