SRX20793941: GSM7512447: ECOR49; Escherichia coli; RNA-Seq
4 ILLUMINA (NextSeq 500) runs: 31.9M spots, 2.4G bases, 1Gb downloads

External Id: GSM7512447_r1
Submitted by: UT Dallas
Study: The distinct transcriptome of virulence-associated phylogenetic group B2 Escherichia coli
show Abstracthide Abstract
Strains of urinary tract associated E. coli both recent isolates and from the ECOR collection and non pathogenic E. coli strains were analyzed. Replicates were performed to establish the reproduciblity, then single experiments were performed there on. Overall design: RNA-Seq
Sample: ECOR49

Name: GSM7512447
Instrument: NextSeq 500
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: cDNA
Layout: SINGLE
Construction protocol: Once grown, cells were collected by centrifugation at maximum speed for 10 minutes at 4 degrees Celsius. Media was decanted and pellets frozen overnight a -80 degrees Celsius. The next day, pellets were thawed on ice and 700 microliters of buffer RLT added. Buffered cells are mechanically lysed using a bead beater set the highest setting for 45 five seconds a cycle for three cycles with a 5 minute rest between cycles. During the rest, the cells are stored on ice. Once lysed, a Qiagen RNeasy mini kit was used to collect RNA. Contaminating DNA was removed though RNase-free DNase digestion of at least 10 micrograms of RNA determined by nanodrop. To remove the DNase and concentrate the RNA, a GeneJet RNA isolation and concentration kit was used. Lexogen RiboCop rRNA depletion kit for Bacteria followed by Illumina Truseq Stranded mRNA library prep kit.
