Sample GSM988178 Query DataSets for GSM988178
Status Public on Dec 03, 2018
Title Sperm Donor Pool H3K9me3 ChIP-seq, rep1
Sample type SRA
 
Source name Sperm donor pool, H3K9me3 ChIP
Organism Homo sapiens
Characteristics cell type: sperm
chip antibody: anti-H3K9me3
antibody vendor: Active Motif
antibody catalog #: 39765
antibody lot #: 01609004
Growth protocol The four sperm donor samples were obtained from men of known fertility attending the University of Utah Andrology laboratory, consented for research. Samples were collected after 2-5 days abstinence, subjected to a density gradient to purify viable, motile, mature sperm, and pooled.
Extracted molecule genomic DNA
Extraction protocol Histone isolation and chromatin immunoprecipitation experiments were performed with sperm pooled from four fertile donors as previously described (Hammoud et al., 2009). For each immunoprecipitation, 10 µL of antibody was coupled to 100 µL of Dynabeads (Invitrogen). Following the ChIP procedure and library preparation (Illumina TrueSeq DNA sample Preparation Protocol), DNA lengths corresponding to mononucleosomes (+ adapters) were gel purified and subjected to sequencing.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer II
 
Description 8349X2
Data processing Basecalls were performed using CASAVA version 1.7.
Reads for H3K9me3 and H3.3 ChIP-seq were aligned using Novoalign V2.07.03 with parameters -rRandom -oSAM to an index containing the hg18 genome (UCSC), Lambda, PhiX, and Illumina Adapter sequences. Reads for H3K36me3, H3K4me1, H3K14ac, and H3K27ac ChIP-seq datasets were aligned with ELAND using the default parameters (Illumina).
Alignments were parsed using NovoalignParser (USeq) or ElandParser (USeq).
ChIP-seq data processing and analysis were performed as previously described in Hammoud et al., 2009. Briefly, differential enrichment between histone ChIP-seq datasets and mononucleosomal control datasets (from GSE15690) were determined with ScanSeqs (USeq), and statistically enriched peaks were called with EnrichedRegionMaker (USeq).
The GSM* numbers for the mononucleosomal controls used were GSM392708-GSM392713, GSM392717-GSM392720 plus approximately 5 million mapped filtered reads randomly subsampled from GSM392701-GSM392707, GSM392714-GSM392716.
