Sample GSM3541187 Query DataSets for GSM3541187
Status Public on Oct 11, 2019
Title 120.4
Sample type SRA
 
Source name Lung
Organism Homo sapiens
Characteristics disease state: IPF
Treatment protocol Following explantation, lungs were inflated to 30 cm H2O and held at 10 cm H2O pressure inflation while frozen over liquid nitrogen vapor according to previously established protocols.(12) The frozen lung was imaged using a high resolution CT scanner and cut into 2 cm thick slices along the transverse plane for sampling. Cores were systematically sampled from each slice using a 1.4 cm diameter coring drill. For this study, 2 cores were randomly selected from each of upper, mid, and lower lung regions for 6 samples per lung.
Extracted molecule total RNA
Extraction protocol RNA was extracted using miRNeasy mini kit (Qiagen) from each core. according the manufacturer’s protocol. RNA concentration and integrity were measured by using NanoDrop ND-2000 and 2200 Tape Station
20 ng RNA input was used for library preparation by AmpliSeq™ Transcriptome Human Gene Expression kit according the manufacturer’s protocol . The cDNA was then amplified and barcoded using the Ion Xpress™ RNA-Seq Barcode 1-16 Kit (Life Technologies 4475485). The Ion PI™ Chip Kit v2 BC (Life Technologies) 4484270) was then loaded using the Ion Chef™ System (Life Technologies 4484177) with the Ion PI™ IC 200 Kit (Life Technologies 4488377). Afterwards, the chips were run on the Ion Proton™ System for Next-Generation Sequencing (Life Technologies 4476610) using the Ion PI™ IC 200 Kit.
