Diagram (A) depicts the gene expression plasmid and the location of the primer pairs used: (a) promoter, (b) beginning of β-globin intron/exon module, (c) end of β-globin intron/exon module, (d) and (e) bacterial plasmid sequence.
(B) Results of the ChIP analysis showing the localization of HP1α, HP1γ, histone H3 di- and tri-MeK9, and Eu-HMTase1 on the gene expression plasmid.
(C) The levels of the associated factors and modifications are plotted.
