Sample GSM77050 Query DataSets for GSM77050
Status Public on Dec 31, 2005
Title Staphylococcus aureus_hydrogen peroxide_20min_replicate2
Sample type RNA
 
Source name Staphylococcus aureus_hydrogen peroxide
Organism Staphylococcus aureus
Characteristics NCTC 8325 Wild type
Biomaterial provider Network on Antimicrobial Resistance in Staphylococcus aureus
Treatment protocol Hydrogen peroxide (10mM)
Growth protocol (i) we initiated S. aureus 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 10mM 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 the RiboPure – Bacteria kit (Ambion, Inc., Austin, TX) 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 500)
Description Hydrogen peroxide treatment
Data processing Affymetrix GeneChip Opererating Software (GCOS) version 1.2
