title: GSM3619473: Control_j rep4; Sus scrofa; miRNA-Seq
library_construction_protocol: Approximately 30 mg of tissue were disrupted via a bead-beating step, and the total RNA, including RNA from approximately 18 nucleotides upwards, was extracted and purified with the miRNeasy Mini Kit (Qiagen). 1 µg of total RNA was used for construction of small RNA sequencing libraries with the NEBNext Multiplex Small RNA Library preparation set for Illumina (New England Biolabs Inc.). Adapter ligated total RNA was reverse transcribed into cDNA, which served as template for PCR amplification (15 cycles) using Illumina´s SR Primer and Index Primers 1-18. Barcoded DNA libraries were purified using the QIAQuick PCR purification protocol (Qiagen) and quantified by DNA 1000 high sensitivity chip (Agilent Technologies). Purified samples were pooled at equimolar (50 nM) concentration. Size selection was performed using gel purification to select for insert sizes between 18 and 50 nucleotides.
