Type: Allele
Species: Mus musculus (mouse)
Chromosome: 5
Alteration at locus: Targeted Mutation
Name: checkpoint kinase 2
Synonyms: Rad53, CHK2
Type: Gene
Species: Mus musculus (mouse)
Chromosome: 5
Alteration at locus: Targeted Mutation
NCBI: 50883

Genetic Alterations
Floxed neo was inserted into exon 9, removed using Cre Recombinase in EIIa mice, leaving a LoxP site. The cytosine coding in position 1113 of mRNA sequence is deleted. This site is analogous to the human position 1100.

    Strain Development
    Mice were crossed with EIIa (mice that express Cre Recombinase in the permanent line) in order to remove the floxed Neomycin resistance gene. Further crosses were with C57BL/6 and Black Swiss mice

    Colony and Husbandry Information

    Colony Surveillance Program and Current Health Reports

    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 .

    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 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 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 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.
