Genetic Alterations
A single loxP site was inserted upstream of exon 2 and a floxed hygromycin resistance cassette was inserted in intron 3. The hygromycin resistance cassette was then selectively excised from correctly targeted ES cells by transient transfection with a cre-expression vector. Exons 2 and 3 were flanked by loxP sites in the resulting ES cells.
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line
    P1 derived from 129S2/SvPas
    Phenotype

    No abnormal phenotype is expected from these conditional mice prior to Cre excision.  Heterozygous and homozygous mice carrying this gene in the germline were indistinguishable from wild-type mice.

    Strain Development
    Developed on 129S2, then crossed to C57BL/6 to get on current mixed background of B6;129S2. Strain Genetic Background Validation: 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, SB9519 (XX ), and CU0798 (XY), at the time of importation. SB9519 is the representative sample selected for the report. The primary (host) background is C57BL/6. The g_FP construct is detected in the sample.

    This sample has more than 2 genetic backgrounds (unexplained regions and/or fractured ideogram). The strain selected for secondary background may be incorrect. The estimation of the contribution of primary and secondary background are likely incorrect.

    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.

    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.
