| Title |
F1r_ChIP_Seq_H3K4me3 (GAII) |
| Sample type |
SRA |
| |
|
| Source name |
Frontal cortex
|
| Organism |
Mus musculus |
| Characteristics |
strain: Cast/EiJ x 129X1/SvJ
chip-antibody: H3K4me3
vendor: Millipore, 04-745
|
| Growth protocol |
The crosses of the two mouse strains 129x1/SvJ (129) and Cast/EiJ (Cast) were performed at Jackson Laboratories (http://jaxmice.jax.org/) 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.

| 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).
