Sample GSM918876 Query DataSets for GSM918876
Status Public on Apr 20, 2012
Title control wild-type strain vs ΔphaEC strain replicate 3
Sample type RNA
 
Channel 1
Source name wild-type strain
Organism Haloferax mediterranei
Characteristics Stage: late exponential
strain: wild-type
Treatment protocol The wild-type strain and ΔphaEC strain were harvested at the late exponential stage.
Growth protocol The wild-type strain and ΔphaEC strain were were cultivated at 37°C to late exponential growth phase in MG medium containing 10 g/L glucose as carbon source.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol (invitrogen) following manufacturer's instructions
Label cy5
Label protocol Fluorescent dye (Cy5 and Cy3-dCTP, Amersham Pharmacia Biotech, Piscataway, NJ) labeled DNA was produced through Eberwine's linear RNA amplification method and subsequent enzymatic reaction. the amplified RNA (aRNA) was purified with NucleoSpin Extract II (MN). We took a cDNA labeling approach with Klenow enzyme after reverse transcription.
 
Channel 2
Source name ΔphaEC strain
Organism Haloferax mediterranei
Characteristics Stage: late exponential
strain: ΔphaEC
Treatment protocol The wild-type strain and ΔphaEC strain were harvested at the late exponential stage.
Growth protocol The wild-type strain and ΔphaEC strain were were cultivated at 37°C to late exponential growth phase in MG medium containing 10 g/L glucose as carbon source.
Extracted molecule total RNA
Extraction protocol Total RNA extracted using Trizol (invitrogen) following manufacturer's instructions
Label cy3

We took a cDNA labeling approach with Klenow enzyme after reverse transcription.
 
 
Hybridization protocol standard CapitalBio Methods
Scan protocol Luxscan 10K (CapitalBio)
Description compare gene expression profiles of wild-type strain with ΔphaEC strain
Data processing After background correction and removal of bad spots, a space and intensity-dependent normalization based on a LOWESS program was employed. For each test and control sample, two hybridizations were performed by using a reversal fluorescent strategy,the geometric mean of lowess normalized log2 ratio (test/control) of two dye-swap slides was calculated. SAM (significance Analysis of Microarrays, version 2.23b) software was used to normalize data.
