Sample GSM1369964 Query DataSets for GSM1369964
Status Public on Sep 29, 2014
Title Control_MCF7_for_HP1_sample_ChIPSeq
Sample type SRA
 
Source name Human breast cells
Organism Homo sapiens
Characteristics cell type: MCF7
chip antibody: none
Growth protocol MCF7 and mCF10 human breast cells were plate and incubated during 72 hours in complete medium (DMEM high glucose GutaMAX life Technologies), then the medium was changed by cross-linking medium containing 1% folmaldehyde.
Extracted molecule genomic DNA
Extraction protocol Performed with Illumina protocol. 10Ng of inmunoprecipitated DNA was end-repaired, and Illumina double stranded adapters for single read sequencing were ligated to the DNA. After purification of the sample with a MinElute spin column, we size-selected libraries on a 2% agarose gel and fragments corresponding to an insert size range of around 130bp were recovered. The libraries were finally amplified with an 18-cycle PCR reaction, and library quality was confirmed on the Agilent 2100 Bioanalyzer. The samples were loaded at concentrations of 8-11 pm onto Illumina single read flowcells and sequenced on the Illumina Genome Analyzer IIx using a 40 cycles recipe.

Description control sample without antibody
Data processing Supplementary_files_format_and_content: Bedgraph files were generated from peak files built from reads mapping uniquely to the genome with at most 0,1,2 mismatches, using Pyicos (Althammer et al., 2011). Significant ChIP-Seq signal was calculated from the coverage of reads comparing each samples with its specific control sample. The significant peaks per sample in bedgraph format are the following: MCF10-HP1-CTRL.MA.pvalue.bedgraph, MCF7HP1-CTRL.MA.pvalue.bedgraph, 4B8-MCF10-CTRL.MA.pvalue.bedgraph, 4B8-MCF7-CTRL.MA.pvalue.bedgraph, MCF10-5metC-CTRL.MA.pvalue.bedgraph, MCF7-5metC-CTRL.MA.pvalue.bedgraph, MCF10-RNAPII-CTRL.MA.pvalue.bedgraph). AGO1 MCF7 Millipore significant peaks were calculated using Pyicos (Althammer et al., 2011).
