Gene Information

Gene Details [Including genotyping protocols]

(provided by MGI)
Transgene: Tg(Cxcl11-cre)KN257Gsat
Name: transgene insertion KN257, GENSAT Project at Rockefeller University
Alteration at locus: Transgenic (cre)
Transgene: cre (Bacteriophage P1)
Name: cre recombinase
Alteration at locus: Transgenic (cre)
Promoter: Cxcl11
Name: chemokine (C-X-C motif) ligand 11
Alteration at locus: Transgenic (cre)

Genetic Alterations:
BAC engineering was used to insert an intron containing cre cassettes, followed by a polyadenylation sequence to terminate transcription of the fusion transcript immediately after the recombinase gene, into the BAC vector at the initiating ATG codon in the first coding exon of the gene. The BAC address for this line is RP23-447A7.

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


In situ histochemistry images of the central nervous system of this mouse can be found at GENSAT. BAC-transgenic images of the central nervous system at various ages of this mouse can be found on the GENSAT project page.

Strain of Origin: FVB/N

Strain genetic background: Mix of FVB/B6/129/Swiss/CD1 stocks

Strain Development: The mice were created in the GENSAT project in collaboration with the Intramural Program of the National Institute of Mental Health. The transgenic mice have a modified BAC-cre injected into pronuclei of FVB/N fertilized oocytes. Hemizygous progeny were mated to non-inbred mice from a mix of FVB/B6/129/Swiss/CD1 stocks. Mice were sent to NIH/NIMH for testing and NIH/NIMH crossed these with ROSA26-GFP mice to get the desired expression for testing. However, the MMRRC will breed all these strains to C57BL/6J and select for mice with only the cre expression, eliminating the ROSA26-GFP from each line. Mice distributed from these strains will only have cre, and not EGFP.

Suggested Control Mice: Wild-type littermates

Colony and Husbandry Information

Special Considerations

In general, GENSAT BAC transgenic mouse lines should be utilized in the hemizygous state. Breeding of the BAC transgene to a homozygous state carries an increased risk of generating an unwanted phenotype for two reasons. First, the transgene inserts at random into the genome. Breeding the transgene to homozygosity results in mice that carry this insertion on both chromosomes, increasing the probability that the insertion will result in an observable phenotype. Second, BAC transgenes may carry passenger genes that are also expressed from the BAC vector. Breeding to homozygosity doubles the number of these genes carried in the transgenic mouse, increasing the possibility that a phenotype will result as a consequence of increased gene dosage. In our experience, observable phenotypes are rare in BAC transgenic mice when carried in the hemizygous state.

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.


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 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.
