title: GSM3591051: CRPC_12-011J3_BLADDER; Homo sapiens; RNA-Seq
library_construction_protocol: Total RNA was isolated from 98 CRPC metastases frozen in Optimal Cutting Temperature compound (OCT; Tissue-Tek) from 55 patients with RNA STAT-60 (Tel-Test). Using an H&E stained slide for each metastatic site for orientation, one millimeter core punches of tumor were obtained, or where appropriate multiple sections enriched for tumor were cut using a Leica CM3050S cryostat. Total RNA was isolated from flash frozen LuCaP xenograft tissue or cell lines with RNA STAT-60 (Tel-Test) followed by purification with RNeasy Mini Kit (Qiagen) utilizing the manufacturer's recommended in solution DNase digestion (Qiagen). RNA-seq libraries were constructed from 1 ug total RNA using the Illumina TruSeq Stranded mRNA LT Sample Prep Kit according to the manufacturer's protocol. Barcoded libraries were pooled and sequenced on the Illumina HiSeq 2500 generating 50 bp paired end reads.
