Sample GSM1312689 Query DataSets for GSM1312689
Status Public on Mar 10, 2014
Title gsexp_iron_deficient_2
Sample type RNA
 
Source name gsexp_iron_deficient_2
Organism Geobacter sulfurreducens PCA
Characteristics genotype: Wild Type
Treatment protocol N/A
Growth protocol Biological triplicates of wild type G. sulfurreducens were harvested during mid-log phase from the three following conditions: fresh water acetate fumarate media (iron sufficient condition), fresh water acetate fumarate media with NO trace iron (iron deficient condition), or ferric citrate acetate media (iron excess condition)
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with TRIzol reagent (Invitrogen). Residual DNA was removed by digestion with DNAse I (Qiagen) followed by purification using the RNeasy Mini kit (Qiagen).
Label Cy3
Label protocol Labeling was performed following the Nimblegen standard operating protocol. See www.nimblegen.com.
 
Hybridization protocol Hybridization was performed by the UCSD GeneChip Core, following the Nimblegen standard operating protocol. See www.nimblegen.com.
Scan protocol Scanning was performed with an Axon GenePix 4000B scanner by the UCSD GeneChip Core, following the Nimblegen standard operating protocol. See www.nimblegen.com.
Description Gene expression of wild type G. sulfurreducens cultured in iron deficient conditions
Data processing Probe level data was normalized with the Robust multi-array analysis (RMA) algorithm without background correction (data in the 6th column of .gff file), as implemented in NimbleScan 2.4 software
Fold changes, log2 difference values, and p-values were calculated. A gene was considered differentially expressed if the log2 difference was >1 and highly differentially expressed if the log2 difference was > 3 with a p-value < 0.05.
