A Cre recombinase expression cassette was inserted into the X-linked Hprt locus by gene targeting in a mouse embryonic stem (ES) cell line isogenic to strain 129S1/SvlmJ (129S1), then the transgene was introduced into 129S1 mice through ES cell chimeras. When females hemizygous for this transgene were mated to males carrying a neomycin selection cassette flanked by loxP sites, the cassette was always excised regardless of Cre inheritance and without detectable mosaicism. The usefulness of this "Cre-deleter" transgenic line is in its efficiency and defined genetic status in terms of mouse strain and location of the transgene.
