Sample GSM443209 Query DataSets for GSM443209
Status Public on Aug 21, 2010
Title F043 vs S044
Sample type RNA
 
Channel 1
Source name F043
Organism Zea mays
Characteristics inbred line: F043
cultivar: flint
tissue: seedling
age: 7 day
sample type: pool of 5 biological replicates
Growth protocol Regulated growth conditions (25℃ 16h-day, 21℃ 8h-night, 70% air humidity) in a climate chamber (Percival Scientific Inc., Perry, USA) for seven days.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with an extraction buffer (200 mM NaCl, 50mM Tris pH 9, 5 mM EDTA pH 8, 1% SDS), phenol/chloroform and selective LiCl (4M) precipitation.
Label Cy5
Label protocol Aminoallyl-RNA was labeled with Cy5 following the "Amino Allyl MessageAmp II aRNA Amplification Kit" protocol (Applied Biosystems/Ambion, Austin, USA).
 
Channel 2
Source name S044
Organism Zea mays
Characteristics inbred line: S044
cultivar: dent
tissue: seedling
age: 7 day
sample type: pool of 5 biological replicates
Growth protocol Regulated growth conditions (25℃ 16h-day, 21℃ 8h-night, 70% air humidity) in a climate chamber (Percival Scientific Inc., Perry, USA) for seven days.
Extracted molecule total RNA
Extraction protocol Total RNA was extracted with an extraction buffer (200 mM NaCl, 50mM Tris pH 9, 5 mM EDTA pH 8, 1% SDS), phenol/chloroform and selective LiCl (4M) precipitation.
Label Cy3
Label protocol Aminoallyl-RNA was labeled with Cy3 following the "Amino Allyl MessageAmp II aRNA Amplification Kit" protocol (Applied Biosystems/Ambion, Austin, USA).
 
 
Hybridization protocol The hybridization and post-hybridization followed the protocol of the Maize Oligo Array Project (http://www.maizearray.org/).
Scan protocol The slides were scanned using an AppliedPrecision ArrayWorx Scanner (Applied Precision Inc., USA).
Description Gene expression data from European maize inbred lines (14 dent, 7 flint)
Data processing Raw data from microarray hybridization, exported from GenePix suites 6.0 (Axon, USA), was imported into LIMMA. The background was corrected by normexp method with offset 50. Background-corrected signal intensities were normalized using a two-step normalization: print-tip group loss (within-array normalization) and then between-array scale normalization.
