title: GSM1195411: seq-Ab2621_H3K79me3_FEM2_AD_Input_Rep1; Caenorhabditis elegans; ChIP-Seq
library_construction_protocol: Worm extract was made from adult worms.  Frozen worm popcorn was ground up in a mixer mill.  Samples were then fixed with 1% formaldehyde for 10 minutes. Chromatin was then sheared by sonication in the Bioruptor, and the soluble fraction was collected and stored at -80°C for future use. Worm extract from adult worms and 5 ?g of affinity purified antibody was used for ChIP. Dynal Protein A or G beads were used to recover the ChIPed DNA.  Samples were then treated with RNase A and Proteinase K, and reverse crosslinked at 65°C. ChIPed DNA was purified and then quantified using the Pico Green HS fluorescent assay. Worm_ChIP-seq_ DNA_Library_Preparation_vSS2. ChIP and 10ng of input are blunted (T4 polymerase), an A-overhang is added (Klenow), DNA is ligated (concentrated T4 ligase) to annealed adaptors, size-selected, and amplified by PCR.Changes: Ligate O/N at 16C. Use adapters and primer cocktail from Illumina TruSeq kit. Use AMPure cleanup in the place of Qiagne cleanup. Use Pippin prep for size selection . Prepared sample are sequenced using Illumina GAII or HiSeq2000 at the High Throughput Sequencing Facility of University of North Carolina at Chapel Hill or Cambridge.
