The EUCOMM targeting vector PG00202_Z_1_D01 inserted into intron 3 an FRT site, lacZ reporter gene, loxP site, neomycin resistance cassette, FRT site and loxP site. A third loxP site was inserted into intron 9. Flp-mediated recombination removed the reporter/selection cassette and left exons 4 through 9 floxed. (J:263623)
