Genetic Alterations
Both, Nxf2 and Nxf3, are X-linked. Intercrossing of Nxf2-floxed and Nxf3-floxed mice eventually led to the production of mice with hemizygous floxed alleles in Nxf2 and Nxf3 mice. Nxf2tm1Jw Nxf3tm1Jw female mice can be crossed with Cre males to generate the Del(XNxf2–Nxf3)1Jw allele (MGI:5297602).
Genotype Determination
ES Cell Line
v6.5 derived from (C57BL/6 x 129S4/SvJae)F1
Phenotype

Homozygous: Mice are viable and fertile with no observed phenotype.

Heterozygous: Mice are viable and fertile with no observed phenotype.

Cre-excised Phenotype: Knockout males suffer from neonatal lethality due to lung dysplasia. Heterozygous males and females display cleft palates. In addition, heterozygous females suffer from partial postnatal lethality, developmental delays, and epilepsy.

Strain Development
Nxf2fl and Nxf3fl mice on mixed genetic backgrounds (B6;129S4) were intercrossed to generate Nxf2fl/+ Nxf3+/fl females, which carried the Nxf2fl and Nxf3fl alleles on separate X chromosomes. Among 49 offspring of Nxf2fl Nxf3fl females mated to wild-type males, we identified one Nxf2fl/Y Nxf3fl/Y male that carried both Nxf2fl and Nxf3fl on the same X chromosome due to meiotic recombination between these two alleles in the Nxf2fl/+ Nxf3+/fl female. This new Nxf2/Nxf3-floxed allele is referred to as Nxffl; the approved symbol for the allele after Cre recombinase-mediated excision of the Nxf fragment is Del(XNxf2-Nxf3)1Jw (MGI ID: 5297602). This allele has been backcrossed to C57BL/6J for two 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@missouri.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.

Cryopreserved material may be available upon request, please inquire to mmrrc@missouri.edu for more information.

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.
