• Mutation details: An IRES-creER cassette, a tetracycline resistance gene, and a Frt-flanked neomycin selection marker were all knocked in to the 3' UTR of the gene. The neomycin selection marker was removed by crossing to a C57BL/6 background Flp recombinase strain. Flp was then bred out of the line. When crossed with a Tg(CAG-Bgeo/ALPP)1Lbe reporter strain and given tamoxifen, cre expression was detected in amacrine cells of the retina, and in a sparse number of cholinergic neurons in the brain.
