The Lrrc4c gene consists of 3 exons. Coding exon 1 was targeted (NCBI accession AK048322.1) by homologous recombination.

Genotype Determination:

ES Cell Line: Lexicon cell line derived from 129S5/SvEvBrd

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

Phenotype

Phenotypic analysis of the F2 mice indicates this mutation affects immunology and neurology.

Phenotypic data provided by Lexicon Genetics, Inc.

Strain of Origin: 129S5/SvEvBrd

Strain genetic background: B6;129S5

Strain Development: Targeted or gene trap mutations are generated in strain 129/SvEvBrd-derived embryonic stem (ES) cells. The chimeric mice are bred to C57BL/6J albino mice to generate F1 heterozygous animals. These progeny are intercrossed to generate F2 wild type, heterozygous, and homozygous mutant progeny. On rare occasions, for example when very few F1 mice are obtained from the chimera, F1 heterozygous mice are crossed to 129/SvEvBrd x C57BL/6 hybrid mice to yield additional heterozygous animals for the intercross to generate the F2 mice.

Mice are archived at the sib-mated generation F2. Recovery will be performed using C57BL/6J donors unless otherwise requested.

Suggested Control Mice:

  • Wild-type littermates

Research Applications

  • Developmental biology
  • Neurobiology

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.

Some MMRRC strains were submitted by the donor as cryopreserved germplasm, see Fees section for further details.

Conditions of Distribution [Including applicable technology transfer agreements]

Distribution of this strain requires execution of the Genentech Lexicon agreement. A link to this form will be provided via email when an order is submitted; the PDF form should be downloaded or the email forwarded to the appropriate institutional representative for completion following directions in the document.

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.

Some MMRRC strains were submitted by the donor as cryopreserved germplasm, and because these strains were not cryopreserved by the MMRRC, we have not assessed the quality of this material. We have extensive experience with recovery of mice from cryopreserved sperm and embryos of varying quality, including using techniques such as IVF and ICSI, and are confident that we will have success in most, if not all, cases. However, because of the unknown quality of these frozen samples, we will restrict recovery efforts to two attempts for each order. Subsequent attempts can be performed on a fee-for-service basis, in addition to the standard fees, upon request.

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.
