Strain Information

Type Congenic; Mutant Strain; Targeted Mutation; Additional information on Genetically Engineered Mutant Mice. Species laboratory mouse Background Strain C57BL/6 Donor Strain 129S4 via J1 ES cell line Generation N13+2pN1pN1   Donating Investigator Rudolf Jaenisch,   Massachusetts Institute of Technology

Description
This strain has loxP sites located on either side of the Ntf3 exon 2. Mice homozygous for this allele are viable, fertile and without behavioral abnormalities. If this strain is crossed with a transgenic strain bearing Cre recombinase, expression of the Ntf3 gene in offspring can be blocked in a tissue-specific manner depending on the promoter controlling the recombinase. Strains under the control of the rat nestin promoter block expression in the central nervous system; see strains 002275 and 002276.

Development
This strain possesses loxP sites introduced on either side of the Ntf3 exon 2.

Supply Details

Standard Supply

Repository-Cryopreserved. Must Be Recovered. Please refer to pricing and supply notes for further information.

Supply Notes

Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. One to two pairs will be recovered to establish a Dedicated Supply of mice. Price by quotation. For more information on Dedicated Supply, please contact JAX® Services, Tel: 1-800-422-6423 or 1-207-288-5845. This strain is included in the Induced Mutant Resource Colony collection. Genomic DNA is available for this strain from the Mouse DNA Resource.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX^® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX^® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX^® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
