Sample GSM2808777 Query DataSets for GSM2808777
Status Public on May 31, 2018
Title 20_8E
Sample type SRA
 
Source name Oocyte
Organism Xenopus laevis
Characteristics Stage: Stage 1
biological replicate: 2
position: Vegetal pole
Extracted molecule total RNA
Extraction protocol 20 oocytes was mounted to OCT medium and sliced using cryostat. RNA was isolated using TRIzol and reprecipitated by 2.5M Lithium Chloride. 500 ng of total RNA was used for rRNA depletion. Illumina TruSeq RNA Sample Prep Kit was used with rRNA depleted RNA for the construction of sequencing libraries.
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Data processing Ribosomal RNA sequences were removed using sortmerna (version 2) and the SILVA rRNA database (version 119). Low quality reads and adaptor sequences were removed using Trimmomatic PE. Reads were aligned against the reference Xenopus laevis genome using STAR (version 2.4.2a).
Annotated reads were counted using htseq-count with the reference model XL9.1_annot_v1.8.1.primary.gff3
Normalized number of reads was generated by DESeq2 using precalculated sizeFactors based on RT-qPCR experiment.

Supplementary_files_format_and_content: Tab-delimited text files include non-normalized and DESeq2 normalized number of reads for each Sample
