    Strain Development
    The replacement vector was derived from an 11-kb EcoRI fragment isolated from a library prepared with DNA from mouse strain 129/Sv. The SmaI fragment containing exon 2 was replaced by a neomycin resistance cassette (phosphoglycerate kinase-neo). The targeting vector was transfected into W9.5 ES cells by electroporation, and transfectants were selected with G418 (350 mg/ml) and FIAU (50 pM). Resistant colonies were screened by Southern blot hybridization with a probe generated from exon 3. 24-well plate at 5 3 105/well for 2 days. Two different clones that had targeted the IFN-gR2 gene by homologous recombination were injected into C57BL/6 blastocysts to generate chimeric mice. Chimeric mice derived from both clones transmitted the mutation to their offspring.
    Suggested Control Mice
    • 129S6/SvEvTac (formerly 129/SvEvTac)
    MMRRC Genetic QC Summary
    The MMRRC Centers have developed a genetic QC pipeline using MiniMUGA array genotyping to provide additional information on strain backgrounds for MMRRC congenic and inbred strains. For more information on when data may be available, or to request genotyping for a strain of interest, please contact mmrrc@med.unc.edu. Older strains may not have this information.
    • There are human immune deficient patients with altered IFN-g receptor genes.

    Order Request Information

    Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.edu for more information.

    Distribution of this strain requires submission of the MMRRC Conditions of Use (COU). A link to the COU web form will be provided via email after an order has been placed; the form should be completed then or the email forwarded to your institutional official for completion.

    The donor or their institution limits the distribution to non-profit institutions only.

    Additional charges may apply for any special requests. Shipping costs are in addition to the basic distribution/resuscitation fees. Information on shipping costs and any additional charges will be provided by the supplying MMRRC facility.

    1 The distribution fee covers the expense of rederiving mice from a live mouse; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.

    2 An aliquot contains a sufficient number of embryos (in one or more vials or straws and based on the transfer success rate of the MMRRC facility) to transfer into one to three recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.

    3 An aliquot is one straw or vial with sufficient sperm to recover at least one litter of mice, as per provided protocols, when performed at the MMRRC facility. The MMRRC makes no guarantee concerning the success of these procedures when performed outside the MMRRC facilities.

    4 The distribution fee covers the expense of resuscitating mice from the cryo-archive; you will receive the resulting litter. The litter will contain at minimum one mutant carrier; the actual number of animals and the gender and genotype ratios will vary. (Typically, multiple breeder pairs can be established from the recovered litter.) Prior to shipment, the MMRRC will provide information about the animals recovered. If you anticipate or find that you need to request specific genotypes, genders or quantities of mice in excess of what is likely from a resuscitated litter, you may discuss available options and pricing with the supplying MMRRC facility.
