Description

Strain Information

Type Congenic; Mutant Strain; Targeted Mutation;
Additional information on Genetically Engineered Mutant Mice.
GenerationN12p+F1pN1
 
Donating Investigator Stanley Korsmeyer,   Dana-Farber Cancer Institute

Description
Mice that are heterozygous for the targeted mutation are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. Homozygous mice are embryonic lethal. These mutant mice may be useful in studies of immune function, including apoptosis, B and T cell development, and bone marrow cell differentiation.

When bred to a strain with loxP sites inserted into the same targeted allele (Stock No. 006088) and a strain with a Cd19 null allele and expressing Cre recombinase during the B lymphocyte development (Stock No. 004126), this mutant mouse strain may be useful in studies of lymphocyte development.

When bred to a strain with loxP sites inserted into the same targeted allele (Stock No. 006088) and a strain expressing interferon inducible Cre recombinase in the lymphocytes (Stock No. 003556), this mutant mouse strain may be useful in studies of lymphocyte development.

Development
A targeting vector containing an internal ribosomal entry site (IRES) fused to a neomycin-beta-galactosidase fusion protein (beta-geo) was used to replace a portion from within exon 1 to within exon 2 of the endogenous gene. This construct was electroporated into 129X1/SvJ-derived RW4 embryonic stem (ES) cells. Correctly targeted ES cells were injected in C57BL/6 balstocysts and the resulting chimeric mice were crossed to C57BL/6J. Heterozygotes were backcrossed to C57BL/6J mice for more than 10 generations prior to arrival at The Jackson Laboratory.

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.

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.
