Genetic Alterations
LoxP sites were introduced upstream and downstream of exons 11 to 13 in the Soat2 gene, which contains active site residues necessary for ACAT2 enzyme catalysis.

    Phenotype

    Homozygous: There is no phenotype related to the homozygous floxed mouse without Cre. When Cre is present, the mutation causes accumulation of polyunsaturated fatty acids in circulating LDL, whereas wild-type mice will predominately have monounsaturated fatty acids in circulating LDL.

    Hemizygous: When Cre is present, the heterozygotes have half the ACAT2 activity of a Cre negative mouse.

    Strain Development
    The Soat2-targeting vector was electroporated into mouse-derived embryonic stem cells (likely of 129S5/SvEvBrd or 129S6/SvEvTac origin). The selected clones were injected into C57BL/6N blastocysts. Acat2-floxed mice were crossed with B6.129S4-Gt(ROSA)26Sortm1(FLP1)Dym/RainJ (RRID:IMSR_JAX:009086), resulting in the excision of the neo cassette and creating Acat2 floxed mice. The homozygous floxed mouse was then crossed with the Alb-Cre mouse, B6.Cg-Speer6-ps1Tg(Alb-cre)21Mgn/J (RRID:IMSR_JAX:003574), bred back to homozygosity for the floxed allele and maintained with sib-matings in which only one sibling was Cre-positive.

    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@med.unc.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.

    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.

    Units Notes
    036815-UNC-EMBRYO Cryo-preserved embryos $1,488.00 / Non-Profit Aliquot Approximate quantity2 : 20-40 embryos / aliquot

    036815-UNC-RESUS Litter recovered from cryo-archive $3,088.00 / Non-Profit 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.
