Colocalization of mH2A1 and mH2A2 with epigenetic markers in carp ribosomal cistron and L41 gene promoters by sequential chromatin immunoprecipitation (ChIP-reChIP) assays. Colocalization of mH2A1 and mH2A2 in the promoter region of (A) the carp ribosomal cistron and (B) the L41 gene with the heterochromatin marker H3K27me2 and the euchromatin marker H3K4me3 in summer (S) and winter (W). Standard deviations are shown in each bar.
