CAG-cre/ERT2 was inserted at the translational initiation Met of the mouse Islr (Meflin) gene in a bacterial artificial chromosome (BAC) genomic clone (B6Ng01-165L10) using recombineering. 4 founders were generated, but line numbers were not indicated. The pound symbol (#) is used when no line is specified and/or lines are pooled. (J:304399)
