(J) Fixed nuclei from CD4+ T cell subsets stained as in Figure 1C. All ChIP data were calculated as n-fold enrichment ratio of immunoprecipitated DNA relative to no antibody control, normalized against total input DNA. NS ChIP enrichment was set to 1 for sequential ChIP. ChIP data with error bars are shown as the mean ± SE of two independent experiments, otherwise representative of at least two independent experiments performed in duplicate.
