Genetic Alterations
Flp mediated recombination was used to remove the neomycin resistance cassette and leave exon 3 flanked by loxP sites, allowing deletion upon introduction of cre recombinase.
Genotype Determination
ES Cell Line
Bruce4 derived from B6.Cg-Thy1a
Phenotype

Homozygous: No observable phenotype.

Heterozygous: No observable phenotype.

Expected Phenotype After Cre-excision: Deletion in all tissues: growth deficit, partially penetrant perinatal lethality, macrocytic anemia, NK cell deficiency, male infertility, etc.

Strain Development
Targeted Bruce4 ES cells derived from B6.Cg-Thy1a were introduced into C57BL/6 albino blastocysts to produce chimeras. Germline transmission to offspring was established by crossing C57BL/6J breeders. Heterozygous animals were bred with Actin-Flp transgenic mice on a C57BL/6J background to delete a Frt-flanked neomycin resistance cassette. Colony has been maintained as heterozygotes by backcrossing to C57BL/6J for at least 10 additional generations.

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 mmrrc@ucdavis.edu 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.

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 litter4; additional fees for any special requests.

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.
