Sample GSM830458 Query DataSets for GSM830458
Status Public on Nov 09, 2014
Title seq-NA_N2_LTemb_Lemb2
Sample type SRA
 
Source name whole body
Organism Caenorhabditis elegans
Characteristics strain: N2
Stage: L3
Treatment protocol Worms are frozen, ground, and crosslinked for 10 minutes in 1% formaldehyde. Later, washed pellets are resuspended in FA buffer and subjected to sonication in a Diagenode Bioruptor (40 pulses of 30 seconds with 1 minute rests in between at full power). Extracts are then spun down and the soluble fraction is stored for quality tests and future ChIP. http://wiki.modencode.org/project/index.php/Worm_popcorn_chromatin_extract_protocol_vSS1:JL:1
Growth protocol Worm_embryo_growth_and_harvest_vSS7. Embryos were prepared by bleaching from gravid N2 adults grown in standard S-basal media liquid culture. Embryos were incubated for 3.5 hours in M9 then frozen in liquid nitrogen. http://wiki.modencode.org/project/index.php/Worm_embryo_growth_and_harvest:JL:SS7
Extracted molecule genomic DNA
Extraction protocol Libraries were prepared according to Illumina's instructions for "Preparing Samples for ChIP Sequencing of DNA", with some variation. DNA was end-repaired using T4 DNA polymerase, Klenow DNA polymerase and T4 DNA polymerase. A's were then added to the 3' ends of the fragments using Kelow fragment (3' 5' exo minus). Paired-end adapters were then ligated onto the ends of the fragments. DNA library was size selected by gel purification, fragments of 250-500 bp were band isolated from an agarose gel. DNA was PCR amplified for 18 cycles. The Bioanalyzer was used to verify fragment purification and quantify DNA.

Description input DNA
Data processing BWA is a fast light-weighted tool that aligns relatively short sequences to a sequence database. The algorithms is based on Burrows-Wheeler Transform (BWT). See the link @ http://bio-bwa.sourceforge.net/. It runs as DEFAULT for both bwa aln and bwa samse. Genome build: ce6
