    Strain Development

    V6.5 embryonic stem cells were injected into C57BL/6 blastocysts and chimeras were born. Chimeras were mated to C57BL/6 wild type mice to generate heterozygotes. Strain is maintained as heterozygotes.

    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.

    MMRRC Genetic QC Summary
    Genetic QC analysis (GQC) was performed on representative samples from the donor submission and provides a baseline reference. Regardless of the material ordered (live mice, sperm, embryos, resuscitated animals), the provided material is guaranteed to contain the primary genetic alteration of interest; however, the composition of the genetic background may vary (See Reproducibility sections of the report for details). The impact of genetic background on previously reported phenotypes has not been evaluated.

    GQC analysis was done on two samples VM41833 (XY), SQ3576 (XX) at the time of importation and the conclusions are consistent in all samples. The results of the analysis are fully congruent with the SDS and VM41833 is the representative sample selected for the report. The primary (host) background is C57BL/6. The secondary (donor) background is derived from an F1 background (B6/129S4) which is consistent with the original nomenclature in the SDS and the background of the targeted allele could be either B6 or S4. Inspection of the ideogram from both samples supports the idea that targeted allele is on an 129S4 background. This can be confirmed by survival analysis in the progeny of het X het crosses. The mitochondrial genome is consistent with at least one backcross to a female from the host background. The Y chromosome is consistent with at least one backcross to a male from the host background. Both samples are heterozygous for the donor background at the locus. The following construct(s) are detected in all samples: bpA, GFP.

    The genome of the MMRRC:34322 strain is 98.2 % inbred and is 89.9% congenic at the strain level. The donor contribution in the linked interval spans 62.4Mb.

    The estimated inbreeding, congenicity, and the relative strain/substrain contribution depend on the number of samples genotyped. The genomes of strains that are not fully inbred are not completely reproducible.

    Colony and Husbandry Information

    Strain is maintained as heterozygotes.

    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.

    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.
