Sample GSM2977274 Query DataSets for GSM2977274
Status Public on Sep 26, 2019
Title WT_B1
Sample type SRA
 
Source name The material is RNA extracted from C. elegans embryos using the Nucleozol preparation protocol from Macherey Nagel.
Organism Caenorhabditis elegans
Characteristics tissue: embryos
genotype: WT
Treatment protocol RNA were extracted from frozen early stage embryos prepared by hypochlorite treatment of young adults
Growth protocol Nematode strain maintenance was as described previously (Brenner, 1974).
Extracted molecule polyA RNA
Extraction protocol RNAs were extracted with NucleoZol [Macherey-Nagel] according to manufacturer’s instructions and treated with DNAse [Turbo-free DNAse, Ambion]. Integrity of RNA was assessed on Tape Station 4200 [Agilent].
RNA-Seq libraries were generated from 500 ng of total RNA using TruSeq Stranded mRNA Sample Preparation Kit (Illumina, Part Number RS-122-2101). Briefly, following purification with poly-T oligo attached magnetic beads, the mRNA was fragmented using divalent cations at 94oC for 2 minutes. The cleaved RNA fragments were copied into first strand cDNA using reverse transcriptase and random primers. Strand specificity was achieved by replacing dTTP with dUTP during second strand cDNA synthesis using DNA Polymerase I and RNase H. Following addition of a single 'A' base and subsequent ligation of the adapter on double stranded cDNA fragments, the products were purified and enriched with PCR (30 sec at 98oC; [10 sec at 98oC, 30 sec at 60oC, 30 sec at 72oC] x 12 cycles; 5 min at 72oC) to create the cDNA library. Surplus PCR primers were further removed by purification using AMPure XP beads (Beckman Coulter) and the final cDNA libraries were checked for quality and quantified using capillary electrophoresis.
