A CMV-hyTK selection cassette flanked by two loxP sites was inserted approximately 2.6kb upstream of exon 1. A third loxP site was inserted into intron 1. ES cells with this mutation were transiently transfected with a vector driving expression of Cre recombinase. ES cells containing only one loxP site, in which the promoter and exon 1 were deleted, were selected. These cells were injected into blastocyts to generate a the allele designated Vhltm1.1Jae.
