Sample GSM879921 Query DataSets for GSM879921
Status Public on Feb 24, 2012
Title H3K36me3_ChIPSeq
Sample type SRA
Source name NIH-3T3_H3K36me3_ChIPSeq
Organism Mus musculus
Characteristics cell line: NIH-3T3
cell type: Mouse embryonic fibroblast cell
chip antibody: H3K36me3

Treatment protocol Cells were cross-linked with 1% formaldehyde in cell culture medium for 10 min at 37C. After quenching with the addition of 125 mM glycine for 5 min at 37C, the cells were washed twice with ice-cold PBS containing proteinase inhibitor. Cells were collected after each wash by centrifugation at 2,500g for 3 min. Finally cells were aliquoted, frozen and kept at -80C.
Growth protocol Standard 3T3 growth conditions: 37C, .05% CO2. Medium was DMEM (Gibco) with 10% FCS (Hyclone). Cells were split 1:8 every 2-3 days.
Extracted molecule genomic DNA
Extraction protocol Lysates were clarified from sonicated nuclei and histone-DNA complexes were isolated with antibody. Libraries were prepared as follows: DNA was end-repaired using a combination of T4 DNA polymerase, E. coli DNA Pol I large fragment (Klenow polymerase) and T4 polynucleotide kinase. The blunt, phosphorylated ends were treated with Klenow fragment (32 to 52 exo minus) and dATP to yield a protruding 3- 'A' base for ligation of Illumina's adapters which have a single 'T' base overhang at the 3’ end. After adapter ligation DNA was PCR amplified with Illumina primers for 15 cycles and library fragments of ~250 bp (insert plus adaptor and PCR primer sequences) were band isolated from an agarose gel. The purified DNA was captured on an Illumina flow cell for cluster generation. Libraries were sequenced on the Genome Analyzer II following the manufacturer's protocols.

Description 31849.0
Data processing Sequence reads were mapped to the mouse genome assembly mm8 using MAQ v 0.7.1, and these alignments were converted to BED format. Read density maps were produced using IGVTools v 1.5.10 to generate a WIG file, which was then converted to BigWig format using the UCSC WigToBigWig conversion utility v 4.
