Enrichment tests of the novel CArG boxes. Bars represent the relative DNA amount of CArG boxes in IPed DNA recovered either with anti-RIN antibody or pre-immune serum (PI) to those in the total input chromatin DNA. (Note that the result for 128R is omitted due to the inadequate amplification efficiency in the real-time PCR analysis.) Data are the means from three independently prepared samples by ChIP with the anti-RIN antibody or the pre-immune serum. Error bars indicate standard error of each mean.
