Sample GSM450500 Query DataSets for GSM450500
Status Public on Dec 11, 2009
Title Reference vs Genotype2 rep1 dye swap
Sample type RNA
 
Channel 1
Source name Oba super 1
Organism Zea mays
Characteristics genotype: Oba super 1
age: at Anthesis
tissue: Earshoot
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using LS TRIzol (Invitrogen, Carlsbad, CA), digested by DNAse, then Rneasy purification kit (Qiagen, Valencia, CA).
Label Cy5
Label protocol The Amino Allyl MessageAmp™ II aRNA Amplification kit (Ambion, Austin, TX) with Cyanine-3 and -5 (GE Healthcare Bio-Sciences Corp., Piscataway, NJ) dyes were used to amplify and label samples.
 
Channel 2
Source name KU1409/4008
Organism Zea mays
Characteristics genotype: KU1409/4008
age: at Anthesis
tissue: Earshoot
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using LS TRIzol (Invitrogen, Carlsbad, CA), digested by DNAse, then Rneasy purification kit (Qiagen, Valencia, CA).
Label Cy3
Label protocol The Amino Allyl MessageAmp™ II aRNA Amplification kit (Ambion, Austin, TX) with Cyanine-3 and -5 (GE Healthcare Bio-Sciences Corp., Piscataway, NJ) dyes were used to amplify and label samples.
 
 
Hybridization protocol Hybridizations were performed overnight in custom designed cassettes in 42 degree water bath, followed by 3 washes.
Scan protocol Scanned on a Genepix 4000B scanner (Molecular Devices Corporation, Sunnyvale, CA). Used GenePix Pro 6.0 (Molecular Devices Corporation) for spotfinding.
Description Reference vs Genotype2 rep1 dye swap
Data processing A Lowess curve was fit to the log-intensity versus log-ratio plot. 20.0% of the data was used to calculate the Lowess fit at each point. This curve was used to adjust the control value for each measurement. If the control channel was lower than 10 then 10 was used instead.
