Knockout of a gene that encodes Nrf2 which encodes exons 4 and 5.  It mirrors the genetic change found in the Nfe2l2 null mouse.  The loxP/FRT flanked Neo cassette is inserted on the 3' side of exon 5 and the single loxP site is inserted on the 5' side of exon 4.  The target region is 2843 bps and includes exons 4-5.  Chimeric mice were crossed to FLP mice to remove the Neo cassette.
