ChIP-qPCR analysis in humanized mouse erythroid cells. H3K4me1, H4ac, GATA1, and NF-E2 p45 ChIP-qPCR analysis in Ter119+ cells isolated from heterozygote humanized mouse. The y-axis represents average enrichment over input DNA from independent ChIPs, normalized to a mouse GAPDH control sequence. Error bars correspond to 1 (± SD) from at least 2 independent ChIPs. Human amplicons () and mouse amplicons () are indicated on the x-axis. MPG indicates intronic sequence in MPG gene; α prom, α globin promoter sequence.
