Genetic Alterations

A loxP-flanked targeting vector containing a reverse tetracycline transactivator (rtTA) in the 5' UTR and a frt-flanked hygromycin cassette downstream of exon 2 was inserted into Ptf1atm1Mgn(Ptf1aLCA) by recombinase mediated cassette exchange (RMCE). rtTA is expressed under control of the endogenous Ptf1a promoter.

ES Cell Line
TL1/TL-1 derived from 129S6/SvEvTac

Homozygous: Lethal

Heterozygous: This mouse line expresses the reverse tetracycline transactivator (rtTA) under control of the Ptf1a regulatory sequences.

Strain Development
The construct was electroporated into 129S6/SvEvTac derived TL-1 embryonic stem (ES) cells. Correctly targeted ES cells were injected into blastocysts. The resulting chimeric animals were crossed to B6;SJL-Tg(ACTFLPe)9205Dym/J to remove the hygromycin cassette. Mice were backcrossed to C57BL/6J for 6 generations. Upon arrival, mice were bred to C57BL/6J for at least 1 generation to establish the colony.
Suggested Control Mice
Wild-type littermates or C57BL/6J mice
  • Diabetes/Obesity
  • Research Tools

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.

TET-System Technology (tetracycline; US 5,814,618; 5,859,310; 7,541,446; 8,383,364 and European Patent EP 0804565)

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.

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.
