Sample GSM1646309 Query DataSets for GSM1646309
Status Public on Mar 31, 2015
Title Glucose time course, 336 hour time point, biological replicate 3
Sample type SRA
 
Source name REL606_glucose-limited minimal medium_336 hr
Organism Escherichia coli
Characteristics strain: REL606
time point: 336 hours
molecule subtype: rRNA-depleted total RNA
Growth protocol Escherichia coli B strain REL606 was revived from a freezer stock via overnight growth in 10 ml Davis Minimal medium supplemented with limiting glucose at 0.5 g/l (DM500) in a 50 ml Erlenmeyer flask. This culture was diluted 100-fold into 50 ml fresh DM500 in a 250 ml Erlenmeyer flask and incubated for 24 hours. To initiate the experiment, these preconditioned cultures were diluted 100-fold into 50 ml fresh DM500 in multiple 250 ml Erlenmeyer flasks and grown for the specified times until harvesting cells for total RNA isolation. All growth steps were conducted with incubation at 37°C and orbital shaking at 120 r.p.m. over a one-inch diameter.
Extracted molecule total RNA
Extraction protocol RNAsnap followed by RiboZero rRNA removal kit for gram-negative bacteria (Epicentre)
RNA was fragmented using the NEBNext Magnesium RNA Fragmentation Module (New England Biolabs). Then, RNA was phosphorylated using T4 polynucleotide kinase and prepared using the NEBNext Small RNA Library Prep Set for Illumina (Multiplex Compatible). DNA fragments greater than 100 bp were excised from a 4% agarose gel after library preparation and recovered using the Zymoclean Gel DNA Recovery Kit (Zymo Research).
