Expression of human Aγ-globin mRNA in transgenic mice containing the BGT50 construct.
S1 nuclease analysis on fetal liver RNA of 15.5-day founder transgenic mice showing that BGT50 is expressed in all 8 animals, including 7 single-copy mice. These data show that the β-globin intron 2 and 3′ enhancer elements are sufficient for reproducible transgene expression when linked to the 5′HS3 element and the β-globin promoter. Abbreviations as described in Figure 3.
