Sample GSM1468953 Query DataSets for GSM1468953
Status Public on Nov 09, 2014
Title C_input
Sample type SRA
Source name lymphoblastoid cell line
Organism Pan troglodytes
Characteristics cell line: lymphoblastoid
antibody: none
Sex: pooled sample from all individuals
Growth protocol cell line source: LCLs from chimpanzee and rhesus macaque individuals were obtained from New Iberia Research Center (University of Louisiana at Lafayette), and New England Primate Research Center (NEPRC, Harvard Medical School)
Extracted molecule genomic DNA
Extraction protocol Chromatin was extracted using protocol described in Cain et al. 2011, except that for some samples, chromatin was sheared with a Covaris S2 (settings: 40 minutes, duty cycle 20%, intensity 8, 200 cycles/burst, 500uL at a time in 12 x 24mm tubes).
Prepared Illumina sequencing libraries as described by the ENCODE Project Consortium (2011), starting with 20 uL of ChIP output or 4 ng of pooled input sample.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Description Control ChIP-seq for Chimpanzee Pooled Individuals
Data processing Basecalls by Illumina CASAVA 1.7.0
Mapped reads to panTro3 and rheMac2 using BWA 0.5.9, allowing up to 2 mismatches per read (-n 2), and excluding gapped alignments (-o 0)
Discarded reads that were assigned with a quality score less than 10 or were duplicates
For Chip-Seq, MACS version 1.4.1 was used to identify sharp peaks of enrichment for H3K4me1, H3K4me3, H3K27ac, and Pol II; RSEG version 0.4.4 was used to classify enrichment of broad genomic regions of enrichment for H3K27me3
For RNA-seq, reads mapped to orthologous exons are counted and summed at gene level
For Chip-Seq, a two-step procedure is used to classify the enriched regions/peaks for each mark
Genome_build: panTro3 and rheMac2 (and hg19 for H_input)
Supplementary_files_format_and_content: bed file format; for ChipSeq they contain peaks and enriched regions identified for each marker; for RNA-seq, they contain number of reads mapped to each gene
