Allele Symbol: Nfatc2tm1Rao
Name: targeted mutation 1, Anjana Rao
Alteration at locus: Knockout
Gene Symbol: Nfatc2
Name: nuclear factor of activated T cells, cytoplasmic, calcineurin dependent 2
Alteration at locus: Knockout
ES Cell Line: Not specified derived from 129/Sv
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.
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.

Fee/unit (US $)
|Litter||Recovered litter1; additional fees for any special requests.|
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.
