Sample GSM2881325 Query DataSets for GSM2881325
Status Public on Feb 05, 2019
Title csrA LB T10 B
Sample type SRA
 
Source name bacterial cells
Organism Salmonella enterica subsp. enterica serovar Typhimurium
Characteristics strain: 14028s
genotype: csrA:: (markerless deletion of CDS after 51st codon)
medium: LB
time point: 10 min post-rifampicin addition
Treatment protocol Samples were treated with 500ug/ml rifampicin and aliquoted collected at the indicated time points and added directly to a stop solution (5% phenol in ethanol). Samples were centrifuged and the stabilized RNA samples frozen at -80C until extraction.
Growth protocol Strains were grown in LB (0.5% yeast extract, 1% NaCl, and 1% tryptone) or mLPM (0.5 uM ferric citrate, 5 mM KCl, 7.5 mM (NH4)2SO4, 0.5 mM K2SO4, 0.3% glycerol, 0.00001% thiamine, 337 uM KPO4, 80 mM MES pH 5.8, and 8 uM MgCl2) medium to mid-exponential phase (OD600 = 0.5 for LB and 0.3 for mLPM)
Extracted molecule total RNA
Extraction protocol Samples were extracted with hot phenol chloroform, treated with Turbo Dnase (Ambion), and cleaned with the RNeasy kit (Qiagen). RNA was normalized using fluorometric methods then an ERCC RNA spike-in was added to all samples (Ambion) to represent 5% of the total sample.
Standard Illumina protocols
 
Library strategy RNA-Seq
Library source transcriptomic
Library selection cDNA
Instrument model Illumina HiSeq 2000
 
Description ST_19
Data processing Basecalls were made with Casava
Reads were aligned to the Salmonella Typhimurium genome and plasmid sequences with bowtie2 using default parameters.
Read counts per gene were determined with Htseq Count
Reads within each time series were normalized to 4 independently collected qRT-PCR decay data for 11 genes
