Sample GSM262739 Query DataSets for GSM262739
Status Public on Mar 31, 2008
Title mESc E14 H3me3K27
Sample type genomic
 
Channel 1
Source name mESc E14
Organism Mus musculus
Characteristics ChIP sample immunoprecipitated with H3me3K27 antibody
Extracted molecule genomic DNA
Extraction protocol ChIP assay was performed following the ChIP protocol provided at http://www.genomecenter.ucdavis.edu/farnham and
http://genomecenter.ucdavis.edu/expression_analysis.
Label Cy5
Label protocol DNA sample (1 μg) was denatured in the presence of 5'-Cy5-labeled random nonamers (TriLink Biotechnologies) and incubated with 100 units (exo-) Klenow fragment (NEB) and dNTP mix [6 mM each in TE buffer (10 mM Tris/1mM EDTA, pH 7.4; Invitrogen)] for 2 h at 37°C. Reaction was terminated by addition of 0.5 M EDTA (pH 8.0), precipitated with isopropanol, and resuspended in water.
 
Channel 2
Source name mESc E14
Organism Mus musculus
Characteristics Total input DNA (control)
Extracted molecule genomic DNA
Extraction protocol ChIP assay was performed following the ChIP protocol provided at http://www.genomecenter.ucdavis.edu/farnham and
http://genomecenter.ucdavis.edu/expression_analysis.
Label Cy3
Label protocol DNA sample (1 μg) was denatured in the presence of 5'-Cy5-labeled random nonamers (TriLink Biotechnologies) and incubated with 100 units (exo-) Klenow fragment (NEB) and dNTP mix [6 mM each in TE buffer (10 mM Tris/1mM EDTA, pH 7.4; Invitrogen)] for 2 h at 37°C. Reaction was terminated by addition of 0.5 M EDTA (pH 8.0), precipitated with isopropanol, and resuspended in water.
 
 
Hybridization protocol 12 ug of the Cy5-labeled ChIP sample and 12 ug of the Cy3-labeled total sample were mixed, dried down, and resuspended in 40 μl of NimbleGen Hybridization Buffer (NimbleGen Systems).After denaturation, hybridization was carried out in a MAUI Hybridization System (BioMicro Systems) for 18 h at 42°C. The arrays were washed using NimbleGen Wash Buffer System (NimbleGen Systems) and dried by centrifugation.
Scan protocol The arrays were scanned at 5-μm resolution using the GenePix 4000B scanner (Axon Instruments)
Description No additional description
Data processing Fluorescence intensity raw data was obtained from scanned images of the oligonucleotide tiling arrays using NimbleScan 2.2 extraction software (NimbleGen Systems). For each spot on the array, log2-ratios of the Cy5-labeled test sample versus the Cy3-labeled reference sample were calculated. Then, the biweight mean of this log2 ratio was subtracted from each point; this procedure similar to mean-normalization of each channel
