FIG. 1.

Schematic presentation of the mouse α-globin locus and the flanking region. Black arrows indicate erythroid cell-specific hypersensitive sites, and green boxes indicate genes. The transcription direction toward centromere (above the line) or telomere (below the line) is indicated by red arrows. A set of NcoI restriction fragments (RF) used for 3C analysis and amplicons (AMP) used for ChIP analysis are shown below the locus. RFs are indicated by roman numerals, and AMPs are shown in arabic numerals. Distances are in kilobases, counting from the ζ-globin mRNA cap site.
