This track represents binding events for the GA-binding protein as assayed by chromatin immunoprecipation on Affymetrix whole genome tiling 2.0R arrays in various cell types.
The data represent peaks based on the array measurements and called by the MAT software (Johnson et al., 2006). The following settings were used: BandWidth = 300, MaxGap = 300, MinProbe = 10, Trim = 0.1, pvalue=1e-5.
These data were performed in biological triplicate. The authors performed Western blots to test the specificity of the antibody, gel electrophoresis to test the proper shearing of chromatin, and qPCR assays of several loci before hybridization to arrays.
