Sample GSM759864 Query DataSets for GSM759864
Status Public on Mar 16, 2012
Title E10.5_forelimb_H3K27ac_ChIP_seq_rep1_index_6
Sample type SRA
Source name embryonic forelimb bud, H3K27ac ChIP
Organism Mus musculus
Characteristics strain: C57BL/6J
tissue: forelimb bud
developmental stage: gestational day E10.5
chip antibody: anti-H3K27ac
antibody vendor: Abcam
antibody catalog #: ab4729
antibody lot#: 961080
sequencing run type: Paired-end 75 multiplexed
Treatment protocol Pregnant mothers were euthanized, and embryos were removed and placed in cold PBS. Forelimb and hindlimb buds were individually removed with forceps.
Growth protocol Normal mouse gestation to day 10.5.
Extracted molecule genomic DNA
Extraction protocol For each ChIP-Seq, limb bud tissue was crosslinked with 1% formaldehyde at room temperature and stored at -80°C. Chromatin was extracted and sheared by sonication. Soluble chromatin was combined with Protein G Dynabeads prebound with appropriate antibodies at 4C overnight. Beads were collected with magnet and washed 5x. Chromatin was eluted with TE+1%SDS at 65C for 10 minutes. Crosslinks were reversed at 65C overnight, and then chromatin was purified with the PCR cleanup kit (Qiagen).

Standard procedure included with the Illumina ChIP-Seq kit (IP-102-1001). For multiplexed samples, Illumina Multiplexing adapters and primers (PE-400-1001) were used instead of those provided with the ChIP-Seq kit. Multiplexed samples were paired-end sequenced with an insert size of 300 bp. Standard procedure included with the Illumina mRNA-seq kit (RS-100-0801).
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Description Chromatin IP against H3K27ac.
Data processing ChIP-Seq alignments: ChiP-Seq reads were aligned with bowtie (0.12.3) to the mouse genome (mm9) retaining only uniquely mapped reads (command: bowtie -m 1 -p 8 -B 1 --solexa1.3-quals ~/GENOME/mm9/dna/mm9_nh).

ChIP-Seq peak calling: ChIP peaks were identified by MACS (1.37) against input controls. Default parameters were used for CTCF ChIP-Seq (input control replicates 1 and 2)(command: macs -t ../../s_6_sequence.aligned -c ../../s_5_sequence.aligned --name=Mouse_CTCF_091310_FL_mfold10_p00001 --format=BOWTIE --tsize=74 --gsize=1860000000 --bw=150 -- pvalue=0.00001 --diag --mfold=10 --wig). Nomodel option was selected for H3K27me3 and H3K27ac ChIP seq (input control replicates 3 and 4 respectively)(command: macs -t ../082310/bowtie/s_5_sequence.aligned -c ../082210/bowtie/s_4_sequence.aligned --name=Mouse_h3k27me3_FL1_p00001 --nomodel --shiftsize=1 --format=BOWTIE --tsi ze=74 --gsize=1860000000 --bw=150 --pvalue=0.00001 --diag).
