title: GSM5619028: Enzalutamide_1; Homo sapiens; Mus musculus; RNA-Seq
library_construction_protocol: Tumor tissue was lysed and homogenized in QIAzol (ref #79306, Qiagen, Hilden, Germany) using an Ultra-Turrax T25 (Janke & Kunkel, Staufen, Germany). Total RNA was isolated using the miRNA-easy mini kit (ref # 217004, Qiagen), and RNA quality was measured using the Bioanalyzer RNA 6000 Nano assay (ref #5067, Agilent, Santa Clara, California, USA). All RNA samples had a RIN value ≥7. Library Prep was performed using the NEBNext Ultra Directional RNA Kit for Illumina according to the protocol "NEBNext Ultra Directional RNA Library Prep Kit for Illumina" (NEB #E7420S/L). mRNA was isolated from total RNA using the oligo-dT magnetic beads. After mRNA fragmentation, cDNA synthesis was performed and used for ligation with adapters and PCR amplification of the resulting product. The quality and yield after sample preparation was measured with the Fragment Analyzer. One sample was re-sequenced due high frequency of multi-mapped reads implicating inadequate depletion of ribosomal RNA.
