These mice carry loxP sites flanking exon 5 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(Stock No.NM-CKO-210174) mice carrying the loxP sites flanking exon 6 of Sorl1 gene. (J:238766)
