Allele Symbol: Ptpn11tm1Toa
Name: targeted mutation 1, Toshiyuki Araki
Alteration at locus: Targeted Mutation
A point mutation of D61Y and a restriction enzyme site was inserted into exon3. By homologous recombination & subsequent removal of the neo cassette that was present & flanked by LoxP site in exon 3.
ES Cell Line: J1 derived from B6.129S6
Homozygous phenotype: Mice that are homozygous for the targeted mutation are not viable.
Heterozygous phenotype: hen used in conjunction with a Cre recombinase-expressing strain, this strain is useful in generating tissue-specific mutants of the floxed allele. This mutant mouse strain may be useful in generating conditional mutations to study cardiac defects, fatal myeloproliferative disorder (MPD) and juvenile myelomonocytic leukemia (JMML).
Founder genetic background: 129S6/SvEvTac
Strain genetic background: B6.129S6
Strain Development: A targeting vector was designed to place a loxP-neo-loxP-STOP-loxP cassette between exons 2 and 3 and to insert a D61Y point mutation and unique AgeI restriction enzyme site in exon 3 of the targeted gene. The construct was electroporated into 129S6/SvEvTac derived W4 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were crossed to C57BL/6 mice for a minimum of 10 generations. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.
Suggested Control Mice: Wild-type littermates

While maintaining a live colony, these mice are bred as heterozygotes. Mice homozygous for the mutation are not viable.
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 email@example.com.
Limited quantities of breeder mice (recovered litter) are available from a cryoarchive; recovered litter usually available to ship in 3 to 4 months.
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.

Fee/unit (US $)
|Litter||Recovered litter1; additional fees for any special requests.|
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.
