Extracted molecule |
genomic DNA |
Extraction protocol |
Chromatin immunoprecipitated experiment was performed as previously described (Beccari et al. 2016). Micro-dissected limb tissues from mouse and chick embryos were cross-linked with 1% formaldehyde/PBS for 15 min at room temperature. Chromatin was sheared and used for each immunoprecipitation with anti-H3K27ac (ab4729, Abcam), anti-H3K27me3 (07-449, Merck Millipore), anti-H3K4me1 (ab8895, Abcam) and anti-CTCF (61311, Active Motif), respectively. Libraries were prepared with at least 5 ng of purified DNA following Illumina TruSeq ChIP library preparation guide. Sequencing was performed with 100-bp single-end.

Description |
chick HH28 WT distal forelimb H3K27ac
|
Data processing |
Demultiplexed ChIP-seq reads were mapped onto the galGal5 or mm10 using Bowtie (Version 0.12.7) (Langmead et al., 2009), with parameters “-m1 –strata –best” according to the conditions described previously (Riising et al. 2014), and PCR duplicates were removed from mapped reads using samtools (Version 0.1.18) (Li et al., 2009) By using bamCompare (Version 2.5.0), The ChIP data from H3K27ac, H3K27me3 and H3K4me1 and the input data were normalized and compared to compute the log2 of the number of reads ratio. The CTCF ChIP data was normalized to obtain 1x depth of coverage by using bamCoverage (Version 2.5.0) (Ramirez et al. 2014, 2016). Peaks of CTCF were called by using MACS2 (Version 2.1.0.20151222) with q-value (0.01) and used for the CTCF motif orientation analysis as previously described (Rodríguez-Carballo et al. 2017) All analysis was done with our Galaxy server (the Bioteam Appliance Galaxy Edition, https://bioteam.net, https://bioteam.net/products/galaxy-appliance) (Afgan et al. 2016). Genome_build: mm10 or galGal5 Supplementary_files_format_and_content: bedgraph of log2 of the normalized number of reads ratio histone marks ChIP versus Input; bedgraph of the normalized 1x depth of CTCF coverage; bed of CTCF narrow peaks with q-value=0.01
