Hprt1^{tm5.1(CAG-Dll4,-Venus)Gos}

The targeting construct introduced into the locus a CAG promoter, loxP site, neomycin resistance cassette, loxP2272 site, the coding sequence with an IRES and Venus reporter cassette, loxP site and loxP2272 site. Cre-mediated recombination removed the selection cassette and allowed for expression of the inserted sequences. (J:224861)
