Sample GSM68687 Query DataSets for GSM68687
Status Public on Aug 15, 2005
Title Pseudomonas aeruginosa_hydrogen peroxide_ 20min_replicate1
Sample type RNA
 
Source name Pseudomonas aeruginosa_hydrogen peroxide
Organism Pseudomonas aeruginosa PAO1
Characteristics Wild type
Biomaterial provider Dr. E. Peter Greenberg’s laboratory at the University of Iowa
Treatment protocol Hydrogen peroxide (1mM)
Growth protocol (i) we initiated P. aeruginosa cultures at 37°C with shaking at 250 rpm using sterilized Luria-Bertani (LB) broth, (ii) after 17 hours, we diluted the overnight cultures 1:100 in pre-warmed LB broth and incubated at 37°C with shaking at 250 rpm until OD600 reached the early logarithmic phase (~ 0.8), and (iii) we re-diluted the cells 1:10 in pre-warmed LB broth and incubated at 37°C with shaking at 250 rpm. Then, we added 1mM hydrogen peroxide immediately after OD600 reached 0.8.
Extracted molecule total RNA
Extraction protocol Total RNA was isolated after 20 min incubation with hydrogen peroxide using RNeasy Mini kit (Qiagen, Inc., Valencia, CA) according to the manufacturer’s protocol.
Label Biotin
Label protocol Approximately 12 µg of total RNA was processed to produce biotinylated cDNA targets.
 
Hybridization protocol Standard Affymetrix procedures
Scan protocol Standard Affymetrix procedures (target signal value was 150)
Description Hydrogen peroxide treatment
Data processing Affymetrix GeneChip Opererating Software (GCOS) version 1.2
