Chromatin immunoprecipitations were performed with cross-linked chromatin from 4 x 10 6 HCT116 cells and either 10 μl of β-Catenin Antibody (Amino-terminal Antigen) or 2 μl of Normal Rabbit IgG #2729 using SimpleChIP ® Enzymatic Chromatin IP Kit (Magnetic Beads) #9003. The enriched DNA was quantified by real-time PCR using using SimpleChIP ® Human Axin2 Intron 1 Primers #8973, SimpleChIP ® Human CaMK2D Intron 3 Primers #5111, human c-Myc promoter primers, and SimpleChIP ® Human α Satellite Repeat Primers #4486. The amount of immunoprecipitated DNA in each sample is represented as signal relative to the total amount of input chromatin, which is equivalent to one.
