Strain Information

Ildr1Gt(D178D03)Wrst
Name: immunoglobulin-like domain containing receptor 1; gene trap D178D03, German Gene Trap Consortium
Synonyms: Ildr1w-
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 16
Alteration at locus: Knockout
Ildr1
Name: immunoglobulin-like domain containing receptor 1
Type: Gene
Species: Mouse
Chromosome: 16
Alteration at locus: Knockout
NCBI: 106347
Homologene: 15892
Genetic Alterations

The gene trap vector (rFlipROSAbetageo (Cre)) inserted into intron 2, 197 bp internal to the exon 2/intron 2 boundary.

Genotype Determination
ES Cell Line
TBV2 derived from 129S2/SvPas
Phenotype

Orogastric administration of fatty acids elevated blood levels of CCK in wild-type mice but not Ildr1-deficient mice.
Homozygous mice are deaf. The donor maintained them as heterozygous, by breeding them to Swiss-Webster mice. Heterozygotes mated produce homozygous as well as wild-type littermates.

Strain Development
Ildr1–/– mice were generated at the Duke Neurotransgenics Facility using the gene-trapped ES cell clone D178D03 TBV-2 cell line (Helmholtz Zentrum Munchen). The targeting vector rFlipROSAβgeo (Cre) contained a 5′ splice acceptor site, followed by β-galactosidase and neomycin phosphotransferase fusion gene insert (β-geo), and finally a bovine growth hormone polyadenylation sequence. The vector was randomly integrated into intron 2 (197 bp internal to the exon 2/intron 2 boundary) of the Ildr1 gene. TBV2 ES cells were grown on irradiated mouse embryonic fibroblasts for two passages, and the presence of the insert was verified by PCR. These ES cells were injected into C57BL/6 blastocysts and transferred to a pseudopregnant female. One fertile chimeric (95% chimeric by coat color) male mouse was born and mated to C57BL/6J mice. Later, the mice were mated to Taconic Swiss Webster (Tac:SW) over the course of 10+ years. Knockout mice were genotyped by PCR.

Colony and Husbandry Information

Cryo-recovered strains distributed by the MMRRC at JAX are shipped to the customer from the Pathogen & Opportunistic-Free Animal Room G200 - see https://www.jax.org/jax-mice-and-services/customer-support/customer-service/animal-health/health-status-reports.

Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email csmmrrc@jax.org.

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 csmmrrc@jax.org 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.
