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.

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).
