Sample GSM1550912 Query DataSets for GSM1550912
Status Public on Aug 20, 2015
Title GM18502_H3K4ME1
Sample type SRA
 
Source name Lymphoblastoid Cell Line
Organism Homo sapiens
Characteristics cell line: GM18502
antibody: H3K4ME1
Treatment protocol Cross linking was performed in 1% formaldehyde for 10 minutes at room temperature. Followed by quenching with Glycin with a final concentration of 125mM
Growth protocol LCLs were grown to a density of 0.6-0.8 x 10^6/mL in RPMI1640 with 15% fetal bovine serum and 1% PenStrep.
Extracted molecule genomic DNA
Extraction protocol For ChIP-Seq, nuclear lysates were sonicated using a Branson 250 Sonifier (power setting 2, 100% duty cycle for 7 x 30-s intervals). Clarified lysates corresponding to 20 million cells were treated with 1-5ug of antibody coupled to Protein G Dynabeads (Invitrogen #10003D, New York). The protein-DNA complexes were washed with RIPA buffer and eluted in 1% SDS TE at 65°C.
ChIP DNA sequencing libraries were generated according to Illumina DNA Tru-Seq DNA Sample Preparation Kit Instructions (Illumina Part # FC-121-2001, San Diego, CA).
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
 
Data processing Personal genomes were created by adding the SNPs of each individual into hg19. SNPs were obtained from the 1000 Genomes Project or imputed using shapeIt and IMPUTE2
ChIP-seq reads were aligned to personal genomes with BWA 0.6.1 (options -q 20, -t 4 and the rest set to defaults)
Peaks were called using MACS2 on merged replicates, subsampled to 50 million single reads. Genome-wide signal tracks (bigWig) were generated using wiggler, also on the subsampled data.
Genome_build: hg19
Supplementary_files_format_and_content: Peaks are in the narrowPeak format. bigWig files were generated using wiggler.
