Sample GSM270866 Query DataSets for GSM270866
Status Public on Jun 02, 2008
Title Arabidopsis cell culture, 4 h_response to phytoprostane A1_rep1
Sample type RNA
Source name cell culture, 4 h treatment with 75µM phytoprostane A1, first replicate
Organism Arabidopsis thaliana
Characteristics mixotrophic cell culture, 4 h treatment with 75 µM phytoprostane A1
Extracted molecule total RNA
Extraction protocol For microarray analysis total RNA was extracted using the RNeasy plant mini kit (Qiagen) according to the manufacturer’s protocol.
Label biotin
Label protocol 1 µg of total RNA was linearly amplified and biotinylated using the One-Cycle Target Labeling Kit (Affymetrix, Santa Clara, CA) according to the manufacturer’s instructions. Labelling and hybridization were conducted by the microarray facility of the Universitaetsklinikum Tuebingen, Germany.
Hybridization protocol 15 µg of labeled and fragmented cRNA was hybridized to Arabidopsis ATH1 Gene Chip® arrays (Affymetrix). After hybridization the arrays were washed and stained in a Fluidics Station 450 (Affymetrix) with the recommended washing procedure. Biotinylated cRNA bound to target molecules was detected with streptavidin-coupled phycoerithrin, biotinylated anti-streptavidin IgG antibodies and again streptavidin-coupled phycoerithrin according to the protocol.
Scan protocol Arrays were scanned using the GCS3000 Gene Chip scanner (Affymetrix) and GCOS 1.3 software. Scanned images were subjected to visual inspection to control for hybridization artifacts and proper grid alignment and analyzed with Microarray Suite 5.0 (Affymetrix) to generate report files for quality control.
Description Three independent replicates were done for each treatment.
Data processing For statistical data analysis the CEL-files were imported into Genespring 7.1 (Agilent Technologies, Santa Clara, CA) using Genesprings implementation of GC-RMA for normalization and probe summarization (Wu et al., 2003). Additionally, genes were median centered by dividing all signal values for a gene by the median of all signals for that gene. Transcripts with a high variance in replicate measurements were removed. From the remaining set genes that show an at least two-fold increase or decrease in average expression were analyzed in a Welsh’s t-test for significant differences and corrected for multiple testing according to Benjamini and Hochberg (1995). Functions of differentially expressed transcripts were annotated using the NetAFFX analysis center.
