Quantification of duplex PCR results. Position of amplicons in the β-globin locus and quantification of chromatin IP results. The ratios of products obtained with the β-globin and amylase primers were determined for each input and Ab-bound sample for the wt and ΔLCR locus. The ratio for the bound fraction is normalized to the input to determine the relative level of enrichment. Enrichment of the globin sequences is reflected by a number >1. The x axis is drawn at 1, reflecting no enrichment. Shown are the averages of enrichment with standard deviation from three independent IPs.
