The galago γ-globin gene promoter has the capability to drive high-level expression of the human γ-globin gene in transgenic mice. For each construct two images of RNase protection assay are shown, each one representing the results from an individual fetus. The line diagrams appearing below each image indicate the tested constructs. Hu γ, 170-bp protected fragment from exon 2 of the human γ-globin gene; Mu ζ, 151-bp protected fragment from the murine ζ-globin gene; Mu α, 128-bp protected fragment from the murine α-globin gene; Bl, blood; YS, yolk sac.
