Sample GSM1091050 Query DataSets for GSM1091050
Status Public on Mar 01, 2013
Title V16 cob, biological replicate 2
Sample type RNA
 
Source name V16 cob
Organism Zea mays
Characteristics developmental stage: V16
tissue: cob
Treatment protocol Three biological replicates per sample were harvested in the middle of the day to minimize complications due to diurnal changes in C and N metabolism.
Growth protocol An elite Syngenta Zea mays (maize) inbred (SRG200) was grown in a greenhouse at the University of Guelph during the summer of 2007. Growth conditions were 16 hour days (~600 μmol m-2 s-1) at 28°C, 8 hour nights at 23°C, and 50% relative humidity. Plants were grown semi-hydroponically in pots containing Turface® clay, watered with a modified Hoagland’s solution containing: 0.4 g/L 28-14-14 fertilizer, 0.4 g/L 15-15-30 fertilizer, 0.2 g/L NH4NO3, 0.4 g/L of MgSO4•7H2O and 0.03 g/L of micronutrient mix (S, Co, Cu, Fe, Mn, Mo and Zn).
Extracted molecule total RNA
Extraction protocol Total RNA was isolated and used for cDNA, cRNA synthesis.
Label biotin
Label protocol Labeling followed a standard protocol recommended by Affymetrix.
 
Hybridization protocol Labeled cRNAs were fragmented and applied to a maize custom GeneChip microarray for molecular hybridization.
Scan protocol The array images with hybridization signals were acquired and quantified by GeneChip Operation System (GCOS) software (Affymetrix).
Description cob_V16_2
Data processing CEL files were normalized using the Robust Multichip Average (RMA) method from the “affy” library of the BioConductor package (version 2.6) of the R statistical framework (version 2.11.0)
