Sample GSM1230269 Query DataSets for GSM1230269
Status Public on Jan 01, 2014
Title P13_rat_kidney_input
Sample type SRA
Source name whole kidney
Organism Rattus norvegicus
Characteristics tissue: whole kidney
strain: Sprague Dawley
age: Postnatal day 13 (P13)
Sex: unsexed
Extracted molecule genomic DNA
Extraction protocol Freshly-isolated kidneys were immediately frozen in liquid nitrogen. To isolate the kidney cortex, a whole adult kidney was kept frozen within a ceramic mortar surrounded by dry ice while the outer ~1mm was shaved off with a razor. Whole kidneys or isolated cortex were thawed and minced in 1% formaldehyde in PBS on ice, followed by rotation for 15 minutes at room temperature. Fixation was quenched with glycine for 5 minutes. Fixed samples were then homogenized with a tissue grinder, washed twice with cold 0.5% IGEPAL CA-630 in PBS, and further disrupted using a type A glass dounce homogenizer. Nuclei were pelleted and sonicated on ice (three 5 minute cycles of 30 seconds on/30 seconds off). A mix of pre-blocked protein A/G beads was used to recover antibody-bound complexes, which were subsequently washed and eluted with SDS-containing buffer. The DNA was purified from the enriched and non-enriched samples by treatment with first RNAse and then Proteinase K, further de-crosslinking overnight at 65C, phenol extraction and ethanol precipitation.
The protocol provided with the ChIP-Seq DNA Sample Prep Kit (Illumina, IP-102-1001) was followed. 200-400bp fragments were selected for sequencing.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2000
Data processing Default settings for the eland_extended algorithm in the Illumina Casava1.8 software were utilized for mapping.
All further analysis on aligned reds was performed using HOMERv3.13 software with default settings. Only one tag per base pair position was considered to remove clonal reads.
Genome_build: rn4
Supplementary_files_format_and_content: Peak files are in the default format generated by HOMERv3.13. Comments in the beginning of peak file contain various parameters of the analysis and column headers. First six columns contain a unique id, chromosome, start location, end location, strand and normalized tag count. Additional statistics are available in columns 7-15.
