摘要

After screening a bacterial artificial chromosome of human genomic DNA library with human HS-40, ζ-, α-, and θ-globin probes, a 110-kb clone bearing the whole human α-globin gene cluster was obtained and rare restriction endonuclease mapping was performed. The bacterial artificial chromosome DNA was isolated, and transgenic mice were generated. Three founders were detected from 35 newborn mice. The copy numbers were 1, 2, and 2, and the expression of human α-globin genes in various tissues at different developmental stages in the transgenic mice was assayed. The human α-globin mRNA can be detected in bone marrow, kidney, liver, brain, but not in muscle, testis, or thymus.
