Sample GSM2027121 Query DataSets for GSM2027121
Status Public on Jan 01, 2017
Title 219
Sample type SRA
 
Source name Rumen
Organism Bos taurus
Characteristics residual feed intake: Low RFI
tissue: rumen epithelial tissue
Extracted molecule total RNA
Extraction protocol rumen tissue samples were frozen on liquid nitrogen, and RNA was extracted using Trizol reagent. Illumina TruSeq RNA Sample Prep Kit (Cat#RS-200-0012) was used with 1 ug of total 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 All the reads were demultiplexed according to their index sequences using CASAVA version 1.8 (Illumina)
Paired end fastq files were mapped to refenrence genome by using Tophat 2.0.10 with default parameters.
The output mapping files from the TopHat2 alignment, along with the GTF file from ENSEMBL (http://uswest.ensembl.org/) rat gene annotation v75.30, were used in the htseq-count (http://www-huber.embl.de/users/anders/HTSeq/) to count the total number of reads mapped to each gene.
The expression level of mRNAs in each library was obtained by normalizing reads number to counts per million reads (CPM): CPM = (gene reads number / total mapped reads number per library) × 1,000,000.
Genome_build: UMD3.1
Supplementary_files_format_and_content: Tab-delimited text files include CPM values for each Sample
