These mice carry loxP sites flanking exon 6 of Sorl1 gene. When crossed with a Cre recombinase-expressing strain, this strain is useful in eliminating tissue-specific conditional expression of Sorl1 gene. While Sorl1-Flox(2)(Stock No.NM-CKO-215075) mice carrying the loxP sites flanking exon 5 of Myc gene. (J:238766)
