Sample GSM238426 Query DataSets for GSM238426
Status Public on Dec 20, 2007
Title Endosperm 72 h; Seed germination; Rep 1
Sample type RNA
Source name Barley Enodsperm from germinating seeds, 72h imbibed
Organism Hordeum vulgare
Characteristics Genotype: Barke cultivar
Age: 72h after imbibition
Treatment protocol endosperm+aleurone (e/a) and embryo+scutellum (em) fractions were dissected from germinating seeds 0, 24, 48 and 72 after imbibition
Growth protocol Seeds were germinated on a moist filter paper in Microclima 1000 growth chambers (Snijders Scientific B.V., Tilburg, Holland) with 16 h light (17oC; 337-377 mmol m-2 s-1 light intensity measured by Sky Quantium light sensor) and 8 h darkness (12oC), 80% humidity.
Extracted molecule total RNA
Extraction protocol PURESCRIPT® RNA isolation kits (Gentra Systems, Inc., Minneapolis, MN) , followed by Rneasy spincolumn cleanup
Label Probe synthesis, labelling and hybridisation were performed according to manufacturer’s protocols (Affymetrix, Santa Clara, CA) at the UCI MicroArray Core Facility, Irvine, Ca.]
Label protocol The BioArray High-Yield RNA Transcript Labeling Kit (Enzo Diagnostics) was then used to synthesize biotin-labeled cRNA from template cDNA by in vitro transcription.
Hybridization protocol 10 µg labeled, fragmented cRNA was then hybridized at 45°C with rotation for 16 hours in an Affymetrix GeneChip Hybridization Oven 320 on Affymetrix Barley1 Genechip arrays. The arrays were washed and stained using streptavidin phycoerythrin on an Affymetrix Fluidics Station 400.
Scan protocol GeneChips were scanned using the GeneChip Scanner 3000
Description Gene expression data from germinationg barley endosperm 72h after imbibition
Data processing The data were analyzed with Microarray Suite version 5.0 (MAS 5.0) using Affymetrix default analysis settings and global scaling as normalization method.
