Sample GSM819254 Query DataSets for GSM819254
Status Public on Jun 18, 2012
Title cgh-1_1
Sample type RNA
 
Source name cgh-1
Organism Caenorhabditis elegans
Characteristics genotype/variation: cgh-1 (tn691) mutant
developmental stage: young adult
tissue: dissected gonads
Treatment protocol Gonads were dissected in M9.
Growth protocol Worms were grown until the young adult stage.
Extracted molecule total RNA
Extraction protocol RNA from gonads was extracted using the PicoPure Kit.
Label biotin
Label protocol RNA was processed according to the GeneChip Whole Transcript (WT) Double-Stranded Target Assay Manual from Affymetrix, fragmented and Biotin labeled using the GeneChip® Hybridization, Wash, and Stain Kit (Affymetrix)/
 
Hybridization protocol Hybridization was performed overnight for 16 h in a GeneChip hybridization oven (Affymetrix).
Scan protocol Scanning was performed with Affymetrix GCC Scan Control v. 3.0.0.1214 on a GeneChip Scanner 3000 with autoloader.
Description SAMPLE 7
Data processing All tiling arrays were processed in R using bioconductor and the packages tilingArray and preprocessCore. The arrays were RMA background corrected and log2 transformed on the oligo level using the following command: expr <- log2(rma.background.correct(exprs(readCel2eSet(filenames,rotated=TRUE)))). We mapped the oligos from the tiling array (bpmap file from www.affymetrix.com) to the c.elegans genome assembly ce6 (www.genome.ucsc.edu) using bowtie allowing no error and unique mappig position. Expressions for individual transcripts were calculated by intersecting the genomic positions of the oligos with transcript annotation (WormBase WS190) and averaging the intensity of the respective oligos.
