| Title |
Oocyte_Cytosol_Rep 2 |
| Sample type |
SRA |
| |
|
| Source name |
Oocyte
|
| Organism |
Xenopus laevis |
| Characteristics |
developmental stage: Stage VI Oocyte
cell fraction: Cytosol
cell type: Oocyte
|
| Growth protocol |
Defolliculated stage VI oocytes were cultured in the oocyte culture medium, or oocyte culture medium containing 2µM progesterone to induce oocyte maturation. All cells were incubated at 18 ℃.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Oocytes and mature eggs were fractionated into the cytosolic, ER, and pellet fractions. Spike mixture was added into each fraction. Total RNAs were extracted using the TRIzol reagent. Before library construction, Ribosomal RNAs was removed with the Ribozero HMR kit (Illumina).
The RNAseq libraries were prepared with Illumina's 'TruSeq Stranded mRNAseq Sample Prep kit' (Illumina). Reads are 100 nt in length.

| Data processing |
Fastq files were generated and demultiplexed with the bcl2fastq v2.20 Conversion Software (Illumina).
Adaptors were trimmed from the 3'-end of the reads. The quality-scores line in fastq files uses an ASCII offset of 33 known as Sanger scores.
Transcripts per million (TPM) were quantified using Kallisto (v 0.46.2) and the Xenopus laevis transcriptome (v 9.2) from the XenBase (http://www.xenbase.org) was used as the reference sequence.
TPM was converted to the absolute concentration by the regression estimation with five spike-in RNAs (egfp, mCherry, mRuby2, firefly, renilla).
Assembly: XENLA_9.2_genome.fa.gz (Xenopus laevis transcriptome)
Supplementary files format and content: tsv files were generated from Kallisto and included TPM values.
Supplementary files format and content: xlsx files contained the absolute concentration, FC, qvalue and proportion of all genes in each fraction.
