Sample GSM751461 Query DataSets for GSM751461
Status Public on Feb 15, 2012
Title F1i_ChIP_Seq_H3K27ac (GAII)
Sample type SRA
Source name Frontal cortex
Organism Mus musculus
Characteristics strain: 129X1/SvJ x Cast/EiJ
chip-antibody: H3K27ac
vendor: Active Motif, AM39133
Growth protocol The crosses of the two mouse strains 129x1/SvJ (129) and Cast/EiJ (Cast) were performed at Jackson Laboratories ( and the male mice F1 offspring and males of each of the two parental strains were shipped to investigator laboratories at 8 to 9 weeks of age.
Extracted molecule genomic DNA
Extraction protocol Frozen mouse frontal cortex from the F1 crosses was thawed on ice and processed with a razor blade into small pieces. Tissue was then crosslinked with formaldehyde, washed, homogenized, and proceeded for ChIP. To isolate chromatin, formaldehyde-cross-linked nuclei were sonicated using a Branson 450 Sonifier (Branson, Danbury, CT). ChIP DNA was subjected to end repair, A-tailing, adaptor ligation, and gel purification. Following PCR amplification for 18 cycles, the final libraries were subjected to sequencing.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer II
Data processing Sequencing reads for the ChIP-Seq reads were mapped using Novoalign (Novocraft, Malaysia) with adapter sequences stripped. Novoalign permits gapped alignment by allowing more than two mismatches per read (up to 8 for high quality base calls on single end reads and 16 on paired-end reads) that particularly benefits sequencing read mapping around SNPs and indels. PCR duplicates for each library were removed with the Picard program(Picard 2011).
