Sample GSM530030 Query DataSets for GSM530030
Status Public on Apr 08, 2010
Title KLF1_ChIPSeq, 3.0
Sample type SRA
 
Source name E14.5 fetal liver, ChIP
Organism Mus musculus
Characteristics tissue: liver
cell type: erythroid
age: E14.5
developmental stage: fetal
strain: Balb/c Klf3 -/-
gender: female
passages: primary tissue
antibody: rabbit polyclonal to KLF1
Growth protocol 4 x Klf3 -/- fetal livers were collected at E14.5 from timed mated female mice, homogenized using a 23G needle, then strained through a 40 micron cell strainer and pooled.
Extracted molecule genomic DNA
Extraction protocol The SOLiD System 2.0 workflow for Lower Input/Lower Complexity DNA fragment library preparation (Applied Biosystems) was followed to prepare libraries containing 80-130bp of ChIP DNA (or Input DNA) flanked by the appropriate adaptors. A detailed description of the method is provided in the Supplemental Experimental Procedures of the publication.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model AB SOLiD System 3.0
 
Description ChIP against KLF1.
Data processing Alignment: Sequencing reads were mapped to the mm9 mouse genome using the mapreads algorithm (Applied Biosystems). In order to maximize the number of mappable reads, we removed the final 5 nucleotides for unmapped reads in a recursive strategy until the reads reached 25 nucleotides in length.

Peaks: We employed the same method used by Chen et al. (2008, Cell 133, 1106-1117) in order to declare a set of KLF1-bound regions for downstream analysis. When generating the tag intensity profile used in peak declaration, we added a count of 1 to each position up to 100bp 3' from the start of each tag. To be declared a peak, a genomic position must pass both a tag intensity threshold and a fold-change threshold. We applied a false discovery rate (FDR) threshold of 1%, which resulted in a tag intensity profile threshold of 9. We applied negative control tag library fold-change threshold of 5.0 at the centre of each declared peak, yielding the final set of 945 declared peaks.
