Sample GSM251038 Query DataSets for GSM251038
Status Public on Apr 21, 2008
Title CNET_031 Replicate 1
Sample type genomic
 
Channel 1
Source name CNET_031 genomic DNA
Organism Campylobacter jejuni
Characteristics Strain CNET_031
Growth protocol Cells from each strain were grown as a confluent lawn on Mueller-Hinton agar plates at 42ºC for 36 Hrs. under microaerophilic conditions prior to genomic DNA isolation
Extracted molecule genomic DNA
Extraction protocol Approximately 1X10^10 cells were harvested and genomic DNA extracted by modified lysis/phenol extraction protocol as described in Taboada et al (2004) J Clin Micro 42:4566-4576.
Label Cy3
Label protocol Approximately 2 µg of genomic DNA was labeled by chemical coupling to Label IT Cy dye as described in Taboada et al (2004) J Clin Micro 42:4566-4576.
 
Channel 2
Source name NCTC_11168 genomic DNA
Organism Campylobacter jejuni
Characteristics Strain NCTC_11168
Growth protocol Cells from each strain were grown as a confluent lawn on Mueller-Hinton agar plates at 42ºC for 36 Hrs. under microaerophilic conditions prior to genomic DNA isolation
Extracted molecule genomic DNA
Extraction protocol Approximately 1X10^10 cells were harvested and genomic DNA extracted by modified lysis/phenol extraction protocol as described in Taboada et al (2004) J Clin Micro 42:4566-4576.
Label Cy5
Label protocol Approximately 2 µg of genomic DNA was labeled by chemical coupling to Label IT Cy dye as described in Taboada et al (2004) J Clin Micro 42:4566-4576.
 
 
Hybridization protocol Equivalent amounts of Cy-3 labelled experimental and Cy-5 labelled control genomic DNAs with similar dye incorporation efficiencies were pooled and co-hybridized overnight to the microarray at 37ºC in DIG-easy hyb solution (Roche). Washes performed as described in Taboada et al (2004) J Clin Micro 42:4566-4576.
Scan protocol Microarrays were scanned using a Chipreader laser scanner (BioRad, Mississauga, ON) according to the manufacturer’s recommendations. Laser power and gain were adjusted to obtain balanced scans on control spots.
Description CGH analysis of Strain CNET_031 vs. Strain NCTC_11168
Data processing Features were extracted using ArrayPro Analyzer version 4.5 and imported into the BioArray Software Environment (BASE version 1.2). Spots flagged due to poor spot morphology or low signal intensity (less than 3 X local background) were filtered out. After print-tip Loess normalization, data was used to calculate the average log ratio [log2(Signal Experimental / Signal Control)] of replicate spots
