Genetic Alterations

In this double KI/KO model, the expression of the mouse Ace2 and Tmprss2 genes is replaced by the expression of the human ACE2 and TMPRSS2 genes.

ES Cell Line
JM8A3
Phenotype
In this mouse model, the expression of the mouse Ace2 and Tmprss2 genes is replaced with expression of the human ACE2 and TMPRSS2 genes. Other than expression of the human genes and inhibition of expression of the corresponding murine genes, this mouse exhibits no known observable or measurable phenotype that differs from the genetic background wildtype strain (C57BL/6N). However, it is anticipated that once exposed to SARS-CoV-2 virus (105), these mice will exhibit signs of disease that are not seen in wildtype mice.

Strain Development
Homozygous ACE2 knockin/Ace2 knockout mice were intercrossed with homozygous TMPRSS2 knockin/Tmprss2 knockout mice, resulting in double heterozygous ACE2/Ace2;TMPRSS2/Tmprss2 mice. These mice were subsequently intercrossed to produce double homozygous ACE2/ACE2;TMPRSS2/TMPRSS2 mice.

Order Request Information

Limited quantities of breeder mice (up to 2 males and 2 females or 4 mice) per investigator per month are available from a live colony, usually available to ship in under 12 weeks. Larger quantities may be available, please contact the distributing center directly at mmrrc@ucdavis.edu for more details.

Cryopreserved material may be available upon request, please inquire to mmrrc@ucdavis.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.

A license from third party patent owner(s) may be required for for-profit entities to use mouse models derived from CRISPR-Cas9 technologies and it is the Users sole responsibility to determine whether such a license is necessary.

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 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.
