Strain Name    :

B6.129S1(Cg)-Mrgprdtm1.1(cre)And/Mmnc

Stock Number :

036118-UNC

Gene Information

Gene Details [Including genotyping protocols]

(provided by MGI)
Target: Mrgprdtm1.1(cre)And
Name: targeted mutation 1.1, David Anderson
Chromosome: 7
Alteration at locus: Knock-In
Target: Mrgprd
Name: MAS-related GPR, member D
Chromosome: 7
Alteration at locus: Knock-In

Genetic Alterations:
Most of the open reading frame was replaced with a cassette containing EGFP, cre, and frt flanked neo that was inserted out of frame with the initiation site. The inserted cassette replaced amino acids 20 through 315 of the total 321 amino acids of the endogenous protein.  The frt-flanked cassette is removed by mating to FLPe deleter mice.

Genotype Determination:

ES Cell Line: CJ7

Strain Description [Including phenotype, strain background, strain development and suggested control mice]

Phenotype

Homozygous mice have significantly diminished sensitivity to cold, heat, and mechanical stimuli in a population of nonpeptidergic neurons. Heterozygouse mice are the same as homozygous, with a lower rheobase, and a relatively higher firing rate following the application of Mrgprd ligands than -/- animals.

Strain of Origin: B6;129S1

Strain genetic background: B6.129S1

Strain Development: Chimeric mice were produced by blastocyst injection and were mated to human β-actin FLPe deleter mice to remove the frt-flanked selection cassette and then were mated to C57BL/6 mice to establish the line. All knock-in lines used for this study were backcrossed to C57BL/6 mice for five or more generations.

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.

Order Request Information

Availability Level

Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.

Conditions of Distribution [Including applicable technology transfer agreements]

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.

Fees

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.

Litter Recovered litter1; additional fees for any special requests.

1 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.

2 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.

3 An aliquot contains a sufficient number of embryos (in one or more vials and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
