A floxed neomycin resistance gene was placed in intron 10 and an additional loxP site was placed in intron 12. Transient transfection of correctly targeted ES cells with a plasmid expressing Cre-recombinase eliminated the neomycin gene along with exons 11 and 12. Absence of protein product in resulting homozygous mice was demonstrated by Western blot analysis. (J:86770)
