Production of macrophage cytokines in response to stimulation with lipopolysaccharide, peptidoglycan and double-stranded RNA is reduced in these Ripk2 KO mice, making them suitable for use in studies of innate and adaptive immune system signaling.
Dr. Richard A. Flavell, Yale University School of Medicine
Rip2 KO mice contain a neo cassette in reverse orientation in place of exons 2-3 of the Ripk2 (receptor (TNFRSF)-interacting serine-threonine kinase 2) gene. Cytokine production in macrophages is reduced in homozygotes upon stimulation with lipopolysaccharide, peptidoglycan and double-stranded RNA, but not with bacterial DNA. RIPK2 deficient cells are also hyporesponsive to signaling through IL1 and IL18 interleukin receptors, and deficient for signaling through NOD (nucleotide-binding oligomerization domain) proteins. T cells show severely reduced NFKB (nuclear factor of kappa light chain gene enhancer in B-cells) activation, IL2 production and proliferation on T cell receptor (TCR) engagement, and impaired differentiation to T-helper subtype 1 (TH1)cells. Western blot analysis of thymocytes demonstrates the absence of protein in homozygous mutant mice. Homozygotes are viable and fertile.
A targeting vector was designed to replace exons 2-3 of the receptor (TNFRSF)-interacting serine-threonine kinase 2 (Ripk2) gene, encoding the active site aspartate residue, with a loxP-flanked neomycin resistance cassette in the opposite orientation to the gene. The vector was linearized and injected into 129S1/Sv-derived W9.5 embryonic stem (ES) cells. Targeted clones were injected into C57BL/6 blastocysts. Resultant chimeric mice were backcrossed to C57BL/6 for 10 generations by the donating laboratory (see SNP note below). Upon arrival at The Jackson Laboratory, mice were bred to C57BL/6J (Stock No. 000664) for at least one generation to establish the colony.
A 32 SNP (single nucleotide polymorphism) panel analysis, with 27 markers covering all 19 chromosomes and the X chromosome, as well as 5 markers that distinguish between the C57BL/6J and C57BL/6N substrains, was performed on the rederived living colony at The Jackson Laboratory Repository. One of the 27 markers on Chromosome 4 is segregating, likly due to targeted mutation. All 5 markers that determine C57BL/6J from C57BL/6N were found to be segregating. These data suggest the mice sent to The Jackson Laboratory Repository were on a C57BL/6N genetic background.

The average number of mice provided from recovery of our cryopreserved strains is 10. The total number of animals provided,
their gender and genotype will vary. We will fulfill your order by providing at least two pair of mice, at least one animal of
each pair carrying the mutation of interest. Please inquire if larger numbers of animals with specific genotype and genders
are needed. Animals typically ship between 10 and 14 weeks from the date of your order. If a second cryorecovery is needed in
order to provide the minimum number of animals, animals will ship within 25 weeks.
The genotypes of animals provided may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation, or that discussed in the strain description. Please inquire about possible genotypes which will be recovered for this specific strain. The Jackson Laboratory 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.
Cryorecovery to establish a Dedicated Supply for greater quantities of mice. Mice recovered can be used to establish a dedicated colony to contractually supply you mice according to your requirements. Price by quotation.
Terms are granted by individual review and stated on the customer invoice(s) and account statement. These transactions are payable in U.S. currency within the granted terms. Payment for services, products, shipping containers, and shipping costs that are rendered are expected within the payment terms indicated on the invoice or stated by contract. Invoices and account balances in arrears of stated terms may result in The Jackson Laboratory pursuing collection activities including but not limited to outside agencies and court filings.
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.
