Sample GSM1620021 Query DataSets for GSM1620021
Status Public on Apr 01, 2015
Title rrf-3
Sample type SRA
 
Source name Total RNA whole animal
Organism Caenorhabditis elegans
Characteristics genotype/variation: rrf-3
developmental stage: adult
transgenes: wormcherry piRNA sensor
tissue: whole animal
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trisure (BioLine) or Trizol (Invitrogen) according to manufacturer's instructions and followed by an overnight precipitation at -20C using isopropanol and glycogen as a carrier. For RIP, custom Anti HRDE-1 polyclonal antibody was generated by Genomic Antibody Technology(GAT) by SDIX (Newark USA) against amino acids 12-161 of HRDE-1.
Before library preparation, 1-5ug of total RNA was treated with 1ul of RNA polyphosphatase (Epicentre) for 30 minutes at 37C. RNA was then extracted using Phenol/chloroform and precipitated overnight at -20C using Ethanol and Sodium Acetate. Following this we followed the Illumina Truseq small RNA protocol according to the manufacturer's instructions
