Sample GSM2881294 Query DataSets for GSM2881294
Status Public on Feb 05, 2019
Title ST_20: RPF WT 4 mLPM
Sample type SRA
 
Source name bacterial cells
Organism Salmonella enterica subsp. enterica serovar Typhimurium
Characteristics strain: 14028s
genotype: wild type
medium: mLPM
Treatment protocol Samples were treated with 100ug/ml choramphenicol for 2 minutes, quick chilled on ice, washed, and frozen with liquid nitrogen
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 Cell pellets were thawed, lysed with bead beating, and treated with micrococcal nuclease to release single monosomes. Ribosomes were isolated by ultracentrifuging lysate over a sucrose cushion. Ribosome protected fragments (RPF) were extracted from the pelleted ribosomes with miRNeasy RNA Extraction Kit (Qiagen) and size selected between 20 and 35 bases with denaturing PAGE.
RNA samples were ligated to a 3' adaptor and reverse transcribed. The cDNA was circularized to add a 5' adaptor then PCR amplified to add sample specific barcodes.
 
Library strategy OTHER
Library source transcriptomic
Library selection other
Instrument model Illumina HiSeq 2000
 
Description ST_20
Data processing Library strategy: ribosome profiling
Basecalls were made with Casava…
Reads were trimmed to remove adaptor sequences and reads shorter than 12 bases were discarded. Reads were aligned to the E. coli rRNA sequences with bowtie with default parameters and unaligned reads were retained
Reads were aligned to the Salmonella Typhimurium genome and plasmid sequences with bowtie using default parameters.
Read counts per gene were calculated with Htseq Count
