Sample GSM475127 Query DataSets for GSM475127
Status Public on Dec 10, 2009
Title 1a NCEP 010308 2-5-08
Sample type RNA
 
Source name colon
Organism Homo sapiens
Characteristics gender: female
Extracted molecule total RNA
Extraction protocol Using a random hexamer incorporating a T7 promoter, double-stranded cDNA was synthesized from 500 ng total RNA from which the majority of the ribosomal RNA had been removed using a RiboMinus Human/Mouse Transcriptome Isolation Kit (Invitrogen, Carlsbad, CA). cRNA was generated from the double-stranded cDNA template though an in-vitro transcription reaction and purified using the Affymetrix sample cleanup module. cDNA was regenerated through a random-primed reverse transcription using a dNTP mix containing dUTP. The RNA was hydrolyzed with RNase H and the cDNA purified. The cDNA was then fragmented by incubation with a mixture of UDG and APE 1 restriction endonucleases; and end-labeled via a terminal transferase reaction incorporating a biotinylated dideoxynucleotide. 5.5 ug of the fragmented, biotinylated cDNA was added to a hybridization cocktail,
Label biotin
Label protocol The cDNA was then fragmented by incubation with a mixture of UDG and APE 1 restriction endonucleases; and end-labeled via a terminal transferase reaction incorporating a biotinylated dideoxynucleotide. 5.5 ug of the fragmented, biotinylated cDNA was added to a hybridization cocktail,
 
Hybridization protocol The hybridization cocktail was loaded on the Human Exon 1.0 ST GeneChip and hybridized for 16 hours at 45oC and 60 rpm
Scan protocol The stained array was scanned at 532 nm using an Affymetrix GeneChip Scanner 3000, generating CEL files for each array.
Description Comparion data--colon tumor and normal were available at (http://www.affymetrix.com/support/technical/sample_data/exon_array_data.affx).
Data processing PARTEK background correction, quantile normalization and probe summarization was performed using RMA
