Sample GSM800625 Query DataSets for GSM800625
Status Public on Mar 15, 2012
Title WT_SA2
Sample type SRA
Source name Chromatin IP against SA2
Organism Mus musculus
Characteristics genotype/variation: wild type
developmental stage: E12.5
cell type: Mouse Embryonic Fibroblasts (MEF)
strain: C57BL/6 x 129 Sv
chip antibody: SA2
Treatment protocol Untreated
Growth protocol MEFs were grown in DMEM supplemented with 20% FBS
Extracted molecule genomic DNA
Extraction protocol Input and chromatin immunoprecipitated DNA samples were provided by the user. Available sample amounts from 4 to 15ng of DNA (as quantitated by fluorometry) were electrophoresed on agarose gel and independent sample-specific fractions of 100-200 bp were taken. Extracted DNA was processed through subsequent enzymatic treatments of end-repair, dA-tailing, and ligation to adapters as in Illumina's "ChIP Sequencing Sample Prep Guide" (part # 11257047 Rev. A), with the exception that gel extraction was replaced with Agencourt AMPure XP (BeckmanCoulter) bead purification. Adapter-ligated library was completed by limited-cycle PCR with Illumina PE primers (14 cycles). The resulting purified DNA libraries were applied to an Illumina flow cell for cluster generation and sequenced on the Genome Analyzer IIx by following manufacturer's protocols.
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina Genome Analyzer IIx
Description WT Mouse Embryonic Fibroblasts
Data processing Image analysis was performed with Illumina Real Time Analysis software (RTA1.8). Sequence alignment to the reference genome (mm9) was made with Illumina's ELANDv2 algorithm on its "eland_extended" mode from within CASAVA-1.7 package. ELANDv2 performs multiseed alignment with consecutive read substrings of 16 to 32 bases separately. The seeds are aligned to multiple candidate positions in the reference genome, with a maximum of two mismatches allowed per 32 bases seed; then they are extended to the full read using gapped alignment, allowing for any number of mismatches and potential gaps (indels) of up to 20 bases. The best alignment among the multiple candidate positions is chosen based on quality scores.
