Genetic Alterations
The BamHI genomic DNA fragment of the mouse Cat gene, containing parts of intron 4 and exon 5, was replaced by a neomycin resistance cassette in the gene targeting vector. The BamHI restriction site located in exon 5 was also purposely disrupted in the targeting vector. Southern blot confirmed recombination. A 50-70% decrease in mRNA was found in heterozygotes and no mRNA was found in homozygotes by Northern blot analysis. Western blot indicated absence of protein in mutant tissue samples. 
Genotype Determination
ES Cell Line
R1 derived from (129X1/SvJ x 129S1/Sv)F1-Kitl+
Phenotype

Homozygous: Mice deficient in catalase are phenotypically normal. Unlike human patients, mice have no clinical manifestations of acatalasemia. No catalase activity could be found in Cat-/- mice. Tissues from Cat knockout mice exhibit a retarded rate in consuming extracellular H2O2, show no increased sensitivity to hyperoxia, and are susceptible to trauma induced dysfunction in brain mitochondria. Catalase deficient lenses are not more susceptible to damage induced by photochemical reaction.

Heterozygous: Cat -/+ mice have ~50% decrease in catalase activity. The brain mitochondria of Cat +/- and Cat -/- mice exhibited a similar sensitivity to CCII-induced impairment of mitochondrial bioenergetic activities.

Strain Development
Correctly targeted R1 ES cells derived from (129X1/SvJ x 129S1/Sv)F1-Kitl+ were identified and microinjected into C57BL/6 blastocysts. Germ line transmission of the targeted allele was achieved by the chimeric mice. Heterozygous knockout mice were interbred to generate homozygous knockout mice. The mice were backcrossed to C57BL/6 for 12 generations, then rederived. The strain was further backcrossed 11+ generations after rederivation, with occasional C57BL/6J mice as wild-type breeders.
Suggested Control Mice
Wild-type littermates or C57BL/6J mice

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@missouri.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.
