title: GSM1642290: 63_cereb; Homo sapiens; RNA-Seq
library_construction_protocol: RNA was extracted from frozen human postmortem samples of cerebellum and frontal cortex using 20-30 mg of tissue. A two-step tissue homogenization method was performed using pestle tips and 21G syringes. Total RNA was extracted using the RNAeasy Plus Mini Kit (QIAGEN, Germantown, MD, USA), as per manufacturer’s instructions. RNA integrity (RIN) was verified on an Agilent 2100 bioanalyzer (Agilent Technologies, Santa Clara, CA, USA) and 100-200 ng of RNA (RIN ≥ 7.0) in a 5 μl volume was used for library preparation and RNA sequencing (RNAseq). Paired-end sequencing libraries were prepared using the TruSeq Stranded Total Sample Preparation kit (Illumina) by the Mayo Clinic sequencing core facilities (Rochester, MN) followed by quality control, cluster generation and sequencing on the Illumina HiSeq 2000 platform. The reads were de-multiplexed and converted to FASTQ format using CASAVA software from Illumina (by the Mayo Clinic core).
