Sample GSM2735894 Query DataSets for GSM2735894
Status Public on Dec 06, 2017
Title RPF MG1655 csrA::kan 1
Sample type SRA
 
Source name bacterial cells
Organism Escherichia coli str. K-12 substr. MG1655
Characteristics strain: K12 MG1655
genotype: csrA::kan (Tn10-mini transposon inserted after codon 51)
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 media to mid-exponential phase (OD600 = 0.5)
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 Ribosome protected fragments (RPF)
EC_6
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 E. coli genome with bowtie using default parameters.
Read counts per gene were calculated with Htseq Count
