title: GSM1303695: beta-catenin ChIP; Homo sapiens; ChIP-Seq
library_construction_protocol: After cross-linking, cells were scraped and sonicated utilizing Diagenode Bioruptor at High setting and cycling 30 seconds ON, 30 seconds OFF. Beta-catenin-DNA complexes were isolated with lab generated anti-beta-catenin antibody . ChIP DNA fragment ends were repaired and phosphorylated using Klenow, T4 DNA Polymerase and T4 Polynucleotide Kinase.  Next, an ‘A’ base was added to the 3’ end of the blunted fragments, followed by ligation of Illumina adapters via T-A mediated ligation.  The ligated products were size selected by gel purification and then PCR amplified using Illumina primers.  The library size and concentration were determined using an Agilent Bioanalyzer.
