Sample GSM1906889 Query DataSets for GSM1906889
Status Public on Dec 31, 2016
Title hns_1
Sample type SRA
 
Source name Enterohemorrhagic Escherichia coli O157:H7 strain EDL933
Organism Escherichia coli O157:H7 str. EDL933
Characteristics genotype: {delta}hns
phase: logarithmic phase
Treatment protocol The bacteria were centrifuged at 4000×g at 4°C for 5 min and then washed with PBS.
Growth protocol Overnight cultures of bacteria were diluted 1:100 in fresh LB broth and grown to logarithmic phase at an OD600 of about 0.8.
Extracted molecule total RNA
Extraction protocol RNA extraction was performed using RiboPure-BacteriaTM Bacteria kit according to the manufacturer's protocol (Ambion, Life Technologies). DNase I treatment was applied to eliminate genomic DNA contamination as per the manufacturer's recommendations.
RNA libraries were prepared for sequencing using standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2500
 
Data processing Illumina Casava1.7 software used for basecalling.
All raw FastQ files generated were filtered using FASTX-Toolkit (http://hannonlab.cshl.edu/fastx_toolkit/).
Reads per kilobase of exon model per million mapped reads (RPKM) was used as a normalized metric to present the gene expression levels.(Nature methods 2008, 5: 621-628)
Transcripts evaluation of differential expression were accomplished using MARS (MA-plot-based method with Random sampling model) in DEGseq package.(Bioinformatics 2010, 26: 136-138)
Genome_build: NC_002655.2
Supplementary_files_format_and_content: RPKM
