008179 B6.129S4-Krastm4Tyj/J
Repository- Live
This strain carries a point mutation (G12D) whose expression is blocked by the presence of a loxP-flanked stop codon. Homozygotes die in utero. Cre-mediated recombination can excise the stop codon and permit the oncogenic protein to be expressed. Intranasal infection with an adenovirus encoding Cre results in a very high frequency of lung tumors and permits controlled timing of tumor initiation and tumor multiplicity. This strain may be useful in studies of cancer and development.

When bred to a strain expressing Cre recombinase under the control of a tetracycline-responsive promoter element and a strain expressing a tetracycline-controlled activator protein in lung epithelial cells (see Stock No. 006234 and 006235 respectively), this mutant mouse strain may be useful in studies of lung development.

006613 STOCK Tg(CAG-Bgeo,-Tle1,-ALPP)1Lbe/J
Repository- Live
Hemizygous transgenic mice are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. These transgenic mice express the mouse transducin-like enhancer of split 1, homolog of Drosophila E(spl) gene, Tle1 (also known as Groucho-related gene 1; Grg1) under the regulation of the chicken beta actin promoter (ACTB) and the cytomegalovirus (CMV) intermediate-early enhancer. An internal ribosome entry sequence (IRES) followed by the human alkaline phosphatase (ALPP) reporter gene inserted downstream of the Tle1 gene directs co-expression of ALPP and TLE1. TLE1 and ALPP co-expression is blocked, however, by the presence of a loxP-flanked Bgeo (beta-galactosidase/neomycin resistance fusion protein) cassette inserted between the ACTB/CMV promoter and the Tle1 coding sequence. In the absence of Cre recombinase, beta-galactosidase activity is detected in all tissues tested including pancreas, lung, kidney, cerebellum, heart, m .....

002674 129-Krastm1Tyj/J
Repository-Cryopreserved
Homozygous mice die at about embryonic day 12-13. They have a hypocellular fetal liver which also displays extensive cell death. They also appear to have a defect in both the hematopoietic cells and their microenvironment.
006439 FVB-Tg(tetO/CMV-KRAS*G12C)9.1Msmi/J
Repository-Cryopreserved
Hemizygous mice are viable and fertile. These Ki-rasG12C transgenic mice express the human KRASG12C mutation under the control of a tetracycline-responsive promoter element (TRE; tetO). When hemizygotes are bred with another transgenic mouse expressing either reverse tetracycline-controlled transactivator protein (rtTA) or tetracycline-controlled transactivator protein (tTA) under the regulation of tissue-specific promoters, transgene expression in the appropriate tissues of the bitransgenic offspring can be regulated with the tetracycline analog, doxycycline.

When crossed with mice containing a lung-specific tTA protein (e.g. Stock Nos. 006222, 006232, 006242 or 006225), treatment with doxycycline results in the formation of benign hyperpl .....

004375 FVB/N-Tg(tetO-Kras2)12Hev/J
Repository-Cryopreserved
Mice that are homozygous for the transgene are viable and fertile. These transgenic mice express activated rat Kras (Kras4bG12D) under the regulation of a tetracycline-responsive promoter element (TRE; tetO). When these mice are mated to strains containing transgenes encoding either rtTA (reverse tetracycline trans-activator protein) or tTA (the tetracycline trans-activator), activated Kras expression in the bitransgenic animals can be induced by administration or withdrawl, respectively, of the tetracycline analog, doxycycline. This strain represents an effective tool for generating tissue specific mutants that would be useful models for studying oncogene activation in human carcinogenesis.

New Strains Under Development The Jackson Laboratory serves as a worldwide distributor and national repository for common and rare strains of inbred mice and mice carrying spontaneous mutations or induced mutations (i.e., transgenic, targeted/"knockout", or chemically induced mutations). At any one time, we have over 100 strains at various stages of development and colony expansion. Strains "Under Development" fall into two categories depending on the anticipated demand from the scientific community.
  1. Strains that will be made available from a live distribution colony at The Jackson Laboratory.
    These strains are designated as: "Under Development for Distribution Colony"
  2. Strains that will be made available through the Cryopreservation Repository.
    These strains are designated as: "Under Development for Cryopreservation Repository"
It is VERY IMPORTANT that you register interest in strains Under Development. The anticipated demand for a strain enables us to determine effectively the distribution plan for each strain Under Development. Registering interest also provides benefits to you (including advance notification of pending availability). Whether a strain is made available from a live colony OR from our cryopreservation repository, you may want to consider the option of Dedicated Supply. To learn more about Dedicated Supply, go to Services.
