Sample GSM155348 Query DataSets for GSM155348
Status Public on Apr 01, 2007
Title Rapid speed under Hydrogen limitation vs. slow speed under hydrogen limitation slide 3000070036B rep 3
Sample type RNA
 
Channel 1
Source name Total RNA from Methanococcus maripaludis grown with 29 ml/min dihydrogen at 0.2 per hour dilution rate
Organism Methanococcus maripaludis
Characteristics grown at rapid speed under hydrogen limitation
Growth protocol cells were grown in chemostats in McCas media gassed with 29 ml/min dihydrogen at 0.2 per hour dilution rate
Extracted molecule total RNA
Extraction protocol Qiagen RNeasy
Label Cy3
Label protocol A variation of aminoallyl cDNA labeling (Ambion), 5-10 ug of total RNA was incubated with 4 ug of random decamers at 75 C for 7 min, reverse transcibed in the presence of 0.15mM aminoallyl UTP for 2 hours at 42 C,the RNA hydrolyzed by NaOH at 65 C for 15 min, neutralized with HEPES, percipitated and resuspended in coupling buffer, NHS-Cy3 was used to couple Cy3 to the aminoallyl UTP, and the reaction cleaned up with minelute columns
 
Channel 2
Source name Total RNA from Methanococcus maripaludis grown with 8 ml/min dihydrogen at 0.042 per hour dilution rate
Organism Methanococcus maripaludis
Characteristics grown at slow speed under hydrogen limitation
Growth protocol cells were grown in chemostats in McCas media with 8 ml/min dihydrogen at 0.042 per hour dilution rate
Extracted molecule total RNA
Extraction protocol Qiagen RNeasy
Label Cy5
Label protocol A variation of aminoallyl cDNA labeling (Ambion), 5-10 ug of total RNA was incubated with 4 ug of random decamers at 75 C for 7 min, reverse transcibed in the presence of 0.15mM aminoallyl UTP for 2 hours at 42 C,the RNA hydrolyzed by NaOH at 65 C for 15 min, neutralized with HEPES, percipitated and resuspended in coupling buffer, NHS-Cy5 was used to couple Cy5 to the aminoallyl UTP, and the reaction cleaned up with minelute columns
 
 
Hybridization protocol 100-120 pmol of Cy3 and Cy5 labeled cDNA where mixed, dried, resuspended in hybridization buffer (Agilent), boiled 3 min, 30 sec on ice, placed on the slide, covered with a coverslip and incubated at 42 C for 14-16 hours in the dark. Slides where washed in 1xSSC + 0.2% SDS then 0.1xSSC + 0.2% SDS at 54 C, washed with 0.1xSSC at room temp then rinsed with water and dried under nitrogen gas.
Scan protocol Scanned on a Molecular Dynamics Gen III array scanner
Images where quantified using TIGR spotfinder
Description Biological replicate 3 of 3. Cultures grown at rapid speed where compared to those under slow growth, both under hydrogen limitation
Data processing Background subtraction followed by LOESS normalization using S+ array analyzer
