Sample GSM1642593 Query DataSets for GSM1642593
Status Public on Mar 25, 2017
Title RNA-seq 37C LB rep1
Sample type SRA
 
Source name Escherichia coli str. K-12 substr. MG1655
Organism Escherichia coli str. K-12 substr. MG1655
Characteristics cell type: Escherichia coli str. K-12 substr. MG1655
Treatment protocol No treatment
Growth protocol Glycerol stocks of E. coli K12 strain MG1655 were inoculated into LB media grown at 37 ℃ with constant agitation overnight. Cultures were diluted 1:100 into fresh minimal medium and then cultured at 37 ℃ to mid-exponential phase (OD600 nm ~ 0.6).
Extracted molecule total RNA
Extraction protocol From the cells cultured in LB media at 37 ℃, total RNA was extracted using RNAsnapTM method, followed by the ethanol precipitation. rRNA was removed using ribo-zeroTM magnetic kit for bacteria in accordance with manufacturer’s instruction (Epicentre). rRNA removal was confirmed using ExperionTM system. Subsequently, 4 µg of the purified RNA was fragmented to sizes of ~300 bp using RNA fragmentation reagent (Ambion, Grand Island, NY).
50 ng of the fragmented RNA was converted to sequencing library using TruSeq® Stranded mRNA Sample Prep Kit in accordance with manufacturer’s instruction (Illumina).
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina MiSeq
 
Data processing Basecalls performed using CASAVA version 1.4
All sequencing reads were mapped to E. coli MG1655 reference genome (NC_000913) using CLC Genomics Workbench5 with the length fraction of 0.9 and the similarity of 0.99.
The expression levels were based upon the RPKM metric obtained from strand-specific manner.
Supplementary_files_format_and_content: RPKM is generated by in-house script
