Sample GSM1709893 Query DataSets for GSM1709893
Status Public on May 24, 2016
Title HuRef_CenpT_X3_(20140710_1,2_7)
Sample type SRA
 
Source name Immunoprecipitated DNA
Organism Homo sapiens
Characteristics cell part: nuclei
cell type: Lymphoblastoid
cell line: HuRef
chip antibody: Anti-CENP-T (Abcam Ab114120)
Extracted molecule genomic DNA
Extraction protocol The HuRef lymphoblastoid cell line was grown in RPMI medium using standard protocols. Cells were fixed at a density equal to 2 million/ml using formaldehyde to a final concentration of 1%. Cross-linking was quenched with 125mM glycine. Chromatin was released from cells by incubating in lysis buffer (1% SDS, 10mM EDTA and 50 mM Tris-HCl (pH 8.1)) on ice for 10 min. The resulting chromatin solution was diluted 10 times with IP dilution buffer (1% Triton X-100, 2mM EDTA, 150 mM NaCl and 20mM Tris-HCl (pH8.1)) . MNase digestion, sonication, pre-clearing and chromatin immunoprecipitation steps were performed as described previously (PMID: 24737864) using antibodies.
 
Library strategy ChIP-Seq
Library source genomic
Library selection MNase
Instrument model Illumina HiSeq 2500
 
Description HuRef cross-linked (X-ChIP) CENP-T ChIP. Replicate with Abcam antibody and pre-clearing.
Data processing Paired reads were merged using SeqPrep (https://github.com/jstjohn/SeqPrep) with parameters -q 30 (quality) and -L 25 (minimum merged pair length). SeqPrep also removed adaptors and low-quality reads. Merged pairs were aligned with various human BACs using the aln/samse functions of BWA version 0.7.5 saving up to 10 alignments per read (-n 10), otherwise with default options. Merged pairs mapped to two consensus sequences representing 20 human centromere sequences are included as supplementary files (Cen1-like and Cen13-like).
