Sample GSM1953717 Query DataSets for GSM1953717
Status Public on Nov 26, 2015
Title R. sphaeroides 2.4.1 (lag90) vs. R. sphaeroides 2.4.1 (exp low) 2
Sample type RNA
 
Channel 1
Source name lag phase (90min)_low aeration
Organism Cereibacter sphaeroides 2.4.1
Characteristics growth phase: lag phase (90min)
aeration condition: low aeration
Treatment protocol R. sphaeroides strains grown under low aeration or aerobic conditions and cells were harvested at different growth phases
Growth protocol R. sphaeroides strains grown under low aeration or aerobic conditions
Extracted molecule total RNA
Extraction protocol Total RNA was isolated by using the hot phenol method (Janzon et al., 1986). After DNase I treatment the RNA was purified by using mixtures of phenol-chloroform-isoamylalcohol and chloroform-isoamylacohol. For microarray analysis the RNA was further purified by RNeasy®MinElute™ spin columns (Qiagen) following the manufacturer’s instructions.
Label Cy3
Label protocol The ULSTM Fluorescent Labeling Kit for Agilent arrays (Kreatech) was used for RNA labeling and fragmentation
 
Channel 2
Source name exponential phase_low aeration
Organism Cereibacter sphaeroides 2.4.1
Characteristics growth phase: exponential phase
aeration condition: low aeration
Treatment protocol R. sphaeroides strains grown under low aeration or aerobic conditions and cells were harvested at different growth phases
Growth protocol R. sphaeroides strains grown under low aeration or aerobic conditions
Extracted molecule total RNA
Extraction protocol Total RNA was isolated by using the hot phenol method (Janzon et al., 1986). After DNase I treatment the RNA was purified by using mixtures of phenol-chloroform-isoamylalcohol and chloroform-isoamylacohol. For microarray analysis the RNA was further purified by RNeasy®MinElute™ spin columns (Qiagen) following the manufacturer’s instructions.
Label Cy5
Label protocol The ULSTM Fluorescent Labeling Kit for Agilent arrays (Kreatech) was used for RNA labeling and fragmentation
 
 
Hybridization protocol Total RNA of three independent experiments (biological replicates 1-3 or 4-6) of two different growth phases were pooled and hybridized to one array. Two arrays were hybridized with independent experimental runs. Gene chip hybridization and scanning were performed according to the specifications from Agilent.
Scan protocol Scanned on an Agilent High Resolution Microarray Scanner. Images were quantified using Agilent Feature Extraction Software (version A.7.5)
Description 2 lag90 vs exp (low)
biological sample 4-6
Data processing LOESS normalization log2 ratio (Cy3/Cy5) with Limma package (v.3.14.3; release date: 2012/11/29) for Bioconductor in R
