GSM9251056: PRRSV; Sus scrofa; miRNA-Seq
Total RNA was extracted using Trizol reagent (thermofisher, 15596018) following the manufacturer's procedure. The total RNA quantity and purity were analysis of Bioanalyzer 2100 and RNA 6000 Nano LabChip Kit (Agilent, CA, USA, 5067-1511) , high-quality RNA samples with RIN number > 7.0 were used to construct sequencing library. Approximately 5 µg of total RNA were used to prepare nine small RNA librariesaccording to the protocol of TruSeq Small RNA Sample Prep Kits (Illumina, San Diego, CA, USA). And then the libraries were sequenced by Illumina Hiseq 2500 at the LC-BIO following the vendor's recommended protocol. Raw reads were subjected to an in-house program, ACGT101-miR (v4.2) to remove adapter dimers, junk, low complexity, common RNA families (rRNA, tRNA, snRNA, snoRNA) and repeats.
