Strain Information

Former Names FVB/N-Tg(WapMyc)212Bri/J    (Changed: 08-AUG-08 ) Type Congenic; Transgenic; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Additional information on Congenic nomenclature. Species laboratory mouse Generation N18   Donating Investigator Eric Sandgren,   Univ of Wisconsin School of Vet Med

Description
Female mice transgenic for the Tg(WapMyc)212Bri are viable and fertile but do not lactate. Mammary glands from pregnant transgenic mice showed enlarged and hyperplastic alveoli with poorly differentiated epithelial cells. Multiparous females develop observable mammary tumors at the average age of 6 months. The majority of tumors were of mixed histotypes with solid as well as glandular or papillary foci. Lung metastases were observed in 3 of 14 tumor-bearing mice. All tumors tested were transplantable into syngeneic mice.

Supply Notes

Cryorecovery - Standard. At least two mice that carry the mutation (if it is a mutant strain) will be provided. The total number of animals provided, their gender and genotype will vary. Please inquire if larger numbers of animals with specific genotypes and genders are needed. IMPORTANT NOTE: The genotypes of the animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description.

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.
