Detailed Description

These mice contain EBV latent membrane protein 1, Lmp1, coding sequence inserted into the Gt(ROSA)26Sor locus. LMP-1 (Epstein-Barr virus latent membrane protein 1) is a six-span transmembrane protein that is a functional, but dysregulated, mimic of CD40 signaling to B cells. Expression of the Lmp1 gene is blocked by a loxP-flanked STOP fragment placed between the Lmp1 sequence and the Gt(ROSA)26Sor promoter. When bred to mice that express Cre recombinase, the resulting offspring will have the STOP cassette deleted in the cre expressing tissue resulting in expression of Lmp1. Mice that are homozygous for the targeted mutation are viable and fertile.

For example, when bred to mice carrying Cd19^tm1(cre)Cgn (Stock No. 006785), Cre recombinase expression results in expression of LMP1 in B cells causing lymphoproliferation and lymphomagenesis.

Development

A targeting vector containing a splice acceptor, a floxed Neo^r-STOP cassette and the EBV latent membrane protein 1 (Lmp1) coding sequence (EBV B95-8 strain derived) was inserted into the Gt(ROSA)26Sor locus. The construct was electroporated into BALB/cJ derived Balb/C-I embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were crossed to BALB/c mice.
Upon arrival at The Jackson Laboratory, the mice were crossed to BALB/cJ (Stock No. 000651) at least once to establish the colony.

We will fulfill your order by providing at least two carriers for each strain ordered. The total number, sex, and genotypes provided will vary, although typically 8 or more animals are provided. Please check genotypes which will be recovered. While the genotypes of all animals produced will be communicated to you prior to scheduling shipment, the genotypes of animals provided may not reflect the mating scheme and genotypes described in the strain description. Animals are typically ready to ship in 11-14 weeks. If a second recovery is required to produce the minimum number of animals, then delivery time would increase to approximately 25 weeks. If we fail to produce animals of the correct genotype, you will not be charged. We cannot guarantee the reproductive success of mice shipped to your facility. If the mice are lost after the first three days (post-arrival) or do not produce progeny at your facility, a new order and fee will be necessary.

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.
