Availability & Fees Order this Strain
A point mutation (G12D – p.Gly12Asp) was placed in the endogenous Nras locus of the LSL-NRasG12D mouse using CRISPR/Cas9 targeting of MMRRC:65292.
HGVS nomenclature (Mutalyzer-confirmed) [Correspondence]
Note: This model also contains an LSL-element that makes the animal Nras-null until Cre is expressed.
This strain is a CRISPR/Cas9-derivative of MMRRC:65292. PCR was used to confirm the absence/presence of the genetic alterations. During Crispr/Cas9 targeting, a silent G/A mutation occurred in the wobble nucleotide of codon 15. The resulting mice were backcrossed two generations to MMRRC:43604 to remove off-target effects before being intercrossed to generate offspring homozygous for the G12D allele. This strain also carries a melanocyte-specific transgene expressing CRE/ERT2.
Colony Surveillance Program and Current Health Reports
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.
A Commercial License Agreement from the Donor is required for for-profit entities to use this strain. For more information, please contact Anissa Thomas.
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.
