    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 XY samples, QR7176 and DN8844, at the time of importation and the conclusions are consistent in all samples. The results of the analysis are congruent with the SDS and DN8844 is the representative sample selected for the report. The primary (host) background is C57BL/6. There is positive evidence of C57BL/6J and C57BL/6N substrains. The secondary background is 129S6 (no mention of this is found in the SDS). There is evidence of a third background, consistent with complex genetics possibly from CD-1 (donor) as indicated in the submission and the SDS as the donor strain. CD-1 is not included in our consensus since it is outbred (represented by gray, unknown). The mitochondrial genome is consistent with at least one backcross to a female from the C57BL/6 background. The Y chromosome is consistent with at least one backcross to a male from the C57BL/6J background. The Cre construct is detected in both samples. The genome of the MMRRC_010588-UNC strain is 88.1 % inbred at the strain level. At least 11.9% of the genome is segregating for the 129S6 and CD1 backgrounds. The level of inbreeding estimated by MiniMUGA is inconsistent with the number of backcross generations reported in the SDS. After ten generations the expected level of inbreeding is >0.955. 21.3% of the genome is segregating for the two substrains (C57BL/6J and C57BL/6N) that contribute to the primary (host) background. The contribution of C57BL/6J is 85.8%, the contribution of C57BL/6N is 7.1%.

    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.

    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.

    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.
