These floxed mutant mice possess loxP sites flanking the single coding exon of the Mgat1 gene. This strain may be useful for generating conditional mutations in applications related to fertilization and embryonic development.

Mice homozygous for this floxed targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. When bred to tissue-specific cre transgenic strains, the loxP-flanked exon is deleted by cre expression.
A targeting vector was used to place a floxed neomycin-thymidine kinase expression cassette downstream of the single coding exon and an additional loxP site upstream of the exon. The construct was electroporated into (129X1/SvJ x 129S1/Sv)F1-Kitl +-derived R1 embryonic stem (ES) cells. Correctly targeted ES cells were transfected with Cre expression plasmid to excise the neo fragment and leave the floxed gene. Gancyclovir-resistant ES cells were injected into blastocysts. Chimeric animals were backcrossed to C57BL/6 more than 6 times by the donating laboratory.
