A gene targeting strategy was used to flank exons 4 and 5 in the Pck1 gene with two tandomly-oreinted loxP sites.
Genotype Determination
  • Genotyping Protocol(s)
  • Center protocol and contact for technical support will be shipped with mice.
  • ES Cell Line
    TL1/TL-1 derived from 129S6/SvEvTac
    Homozygous: Pcklox/lox animals are viable. Pck1 activity and protein content in liver and kidney do not differ from wild-type.

    Heterozygous: These animals are also viable and do not differ from the wild-type.

    Strain Development

    After achieving germline transmission mice carrying the pcklox/lox allele were bred to B6.Tg(Alb-cre)21Mgn/J transgenic animals. Subsequently, the transgene was segregated from the pcklox/lox allele, and the animals were interbred to obtain the current pcklox/lox line.

    A sample from this MMRRC strain was analyzed using the Mouse Universal Genotyping Array (MUGA) and MMRRC computational tools were used to assess the genetic background. A summary of the data can be found here.

    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.

    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.
