Genotype Determination:

  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line: Not specified derived from 129/Sv

    Phenotype

    Complete loss of NFAT1 protein due to disrupted gene. Increased type II responses to inflammatory stimuli including eosinophilia and increased IgE levels and cytokine production.

    Mammalian Phenotype Terms:
    Allelic Composition: Nfatc2tm1Rao/Nfatc2tm1Rao (Genetic Background: B6.Cg-Nfatc2tm1Rao )

    Strain of Origin: 129/Sv

    Strain Development: Founders on a mixed 129/SvJ and C57BL/6J background were crossed to C57BL/6 mice, subsequent heterozygotes were backcrossed to C57BL/6 for 4 generations giving a total of 5 backcrosses before sib mating was undertaken.

    Strain Genetic Background Validation: A sample from this MMRRC strain was analyzed using the Mouse Universal Genotyping Array (MUGA) and MMRRC computational tools were used to assess the genetic background. A summary of the data can be found here.

    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.

    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 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.

    2 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.

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