Information from provider

ProviderZbynek Kozmik
Provider affiliationDept. of Transcriptional Regulation, Institute of Molecular Genetics AS CR, v.v.i.
Genetic informationA BAC clone (RP24-82D21) containing 200kb covering the mouse Rx locus was modified by insertion of Cre recombinase into the first ATG of the Rx gene. The Cre-inserted BAC was used for pronuclear injection.
Phenotypic informationCre recombinase is expressed in the pattern corresponding to the endogenous Rx gene: in optic vesicles and ventral forebrain from E9.0 embryos and later in retina and ventral forebrain.
Breeding historyThis mouse strain was crossed 4x to C57BL/6NCrl. Breeding takes place only by crossing WT x tg mice.
