Type Mutant Stock; Targeted Mutation; Species laboratory mouse Donating Investigator Silvia Arber, Friedrich Miescher Institute Description
This strain expresses Cre recombinase from the endogenous Pvalb, parvalbumin, locus. When crossed with a strain containing loxP site flanked sequence of interest, Cre-mediated recombination results in tissue-specific deletion of the target. Recombination occurs in more than 90% of neurons that express parvalbumin, such as interneurons in the brain and proprioceptive afferent sensory neurons in the dorsal root ganglia. This mutant mouse strain represents a model that may be useful in studies of neuronal differentiation.Development
An IRES-Cre-pA targeting cassette containing cre coding sequence, internal ribosome entry site (IRES), and polyadenylation site sequence was inserted into the 3' UTR of exon 5. The endogenous Pvalb promoter drives expression of the Cre recombinase. The construct was electroporated into 129P2/OlaHsd-derived E14 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were crossed to C57BL/6 mice. Heterozygotes were intercrossed to produce homozygotes.

Please note: Estimated available for sale dates are provided to keep customers better informed on strains under development. Please note that our Colony Managers routinely monitor the target date and edit it based on breeding performance and other factors. The length of time it takes to make a new strain available for sale depends on genotype, age, number of animals sent by the Donating Investigator, breeding performance, additional strain development (backcrossing, making homozygous), and anticipated demand for the strain/interest registered.
