产品应用：The β-galactosidase-neomycin phosphotransferase fusion gene (βgeo)-trapped reverse orientation splice acceptor βgeo line 26 (ROSA26) locus was modified by gene targeting such that βgeo is expressed only after Cre-mediated excision of loxP-flanked DNA sequences. These mice may prove useful in the study of cell fate and cell migration during embryogenesis through recombinase-activated tagging.
