Allele Symbol: Sod2tm1Cje
Name: targeted mutation 1, Charles J Epstein
Alteration at locus: Knockout
Gene Symbol: Sod2
Name: superoxide dismutase 2, mitochondrial
Alteration at locus: Knockout
ES Cell Line: CB1-4Ê derived from C57BL/6J x (Rb(11.16)2H x Rb(16.17)32Lub)F1
The heterozygous mutants have no overt phenotype. The homozygous mutants have an early lethal phenotype. About 60% of the homozygous mutants die around E15, the other live to term but usually die within 24 hours after thay are born.Mammalian Phenotype Terms:

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