Genetic Alterations

This strain is a derivative of MMRRC:43604 ("LSL-NRasQ61R"). A single point mutation (Q61L – p.Gln61Leu) was placed in the endogenous Nras locus of the LSL-NRasQ61R mouse using CRISPR/Cas9 targeting. This strain also carries a melanocyte-specific transgene expressing CRE/ERT2.

Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • Phenotype
    Homozygous: No defects in development or fertility observed.
    Hetero/Hemizygous: No defects in development or fertility observed.
    Cre-excised Phenotype: When treated topically with 4-hydroxytamoxifen to induce melanocyte-specific CRE activation, these mice spontaneously develop cutaneous melanoma. Otherwise, the mice appear phenotypically normal.

    Strain Development
    CRISPR/Cas9 targeting of MMRRC:43604 to introduce the alteration as described above. The resulting mice were backcrossed two generations to MMRRC:43604 before being intercrossed to generate homozygotes. This strain also carries a melanocyte-specific transgene expressing CRE/ERT2.

    Note: This strain belongs to a mini-collection that includes MMRRC:65288, 65289, 65290, 65291, 65292, 68060, 68061, and 68062.

    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.

    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
    065289-UNC-RESUS Litter recovered from cryo-archive $2,914.00 / Non-Profit Litter Recovered litter4; additional fees for any special requests.
    Cryopreserved material may be available upon request, please inquire to mmrrc@med.unc.edu for more information.

    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.
