Figure 3From: Persistent Fetal γ-Globin Expression in Adult Transgenic Mice following Deletion of Two Silencer Elements Located 3′ to the Human Aγ-Globin GeneChromosomal sites of transgene integration analyzed by FISH. Sites of chromosomal transgene integration are shown (arrow) for the control (LCR Aγ-C, LCR Aγ-F, and LCR Aγ-H) and for the single copy (LCR-Aγ-ΔEnh/F-1, 2, and 3) lines used in this study.Back to article page
