    Phenotype

    Homozygous: DNase X KO

    Hetero/Hemizygous: Normal

    Cre-excised Phenotype: Undetermined

    Strain Development
    Transgenic animals were generated by standard techniques using a commercial provider (mice and more/ Hamburg, Germany - Curator's note: This company no longer exists). The targeting vector was constructed to contain the neomycin resistant gene (neo) and 4 of the downstream coding exons (exons 5-8). A HSV-TK cassette was inserted downstream of the modified gene for negative selection. Targeting construct was eletroporated into E14 embryonic stem (ES) cells, and cells were cultured to obtain G418-positive clones. The homologous recombination event was verified by PCR and the recombinant clone was injected into C57BL/6 recipient blastocysts which were transferred into pseudopregnant females. Genotyping of offspring was carried out by PCR amplification of genomic DNA using primers that flanked the neo insertion site in intron 1 and 4 as well as primers in deleted exons and the neo sequence. The absence of DNase X mRNA in mutant mice was verified by a RT-PCR assay.

    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.

    Colony and Husbandry Information

    For breeding, mice must be kept in a dark, quiet place to avoid females attacking males.

    Colony Surveillance Program and Current Health Reports

    Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email mmrrc_health@med.unc.edu.

    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.

    Units Notes
    043541-UNC-EMBRYO Cryo-preserved embryos $1,404.00 / Non-Profit Aliquot Approximate quantity2 : 20-40 embryos / aliquot
    043541-UNC-SPERM Cryo-preserved spermatozoa $564.00 / Non-Profit Aliquot Approximate quantity3

    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.
