Sample GSM261045 Query DataSets for GSM261045
Status Public on Apr 29, 2009
Title after 3 days in mannitol medium rep1
Sample type RNA
Source name 100904A_DH46_4d1
Organism Hordeum vulgare
Characteristics after 3 days in mannitol medium
Treatment protocol Anthers extracted from the spikes under a stereoscopic microscope were inoculated in a treatment medium containing 0.7 M mannitol, 40 mM CaCl2, and 8 g/l agarose, and kept at 25 C in the dark for 4 days (Cistue´et al. 2003). Samples were collected before and after 4 days in mannitol medium. Three samples from each step were harvested and used for microarray analysis.
Growth protocol Donor plants were grown in growth chambers with controlled temperature (18-21ºC), relative humidity (70-80%) and photoperiod (16 h light), as described by Cistué et al. (2003).
Extracted molecule total RNA
Extraction protocol Total RNA was isolated using TRIzol reagent (Invitrogen) from frozen crown samples taken from above soil tissue excluding most fully extended lamina. The protocol is available on the Arabidopsis Information Resource website at RNA was purified using Qiagen RNeasy spin columns with DNase treatment. Quality was assessed by running 25-250 ng on a RNA Lab-On-A-Chip (Caliper Technologies) using an Agilent Bioanalyzer 2100 (Agilent Technologies).
Label biotin
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 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 The arrays were scanned on a Hewlett-Packard GeneArray scanner.
