Type JAX® GEMM® Strain - Mutant Strain Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Transgenic Species laboratory mouse Donating Investigator Dennis Selkoe, Brigham & Women’s Hsp, Harvard Med Schl Strain Description
These transgenic mice express human membrane metallo-endopeptidase (MME) under the direction of the mouse calcium/calmodulin-dependent protein kinase II alpha (Camk2a) promoter. Transgene expression is approximately 8 fold relative to wildtype controls, as detected by quantitative Western blot analysis and protease activity assay. The levels of soluble alpha beta-amyloid X-40 and soluble alpha beta-amyloid X-42 are reduced in 2 to 3 month old transgenic mice. Mice that are hemizygous for the targeted mutation are viable, normal in size and do not display any gross physical or behavioral abnormalities. Transgenic mice have poor reproductive performance. When crossed to B6.Cg-Tg(PDGFB-APPSwInd)20Lms/2J (Stock No. 006293) mice, amyloid beta plaques do not develop in the resulting double transgenic mice. This mutant mouse strain may be useful in studies of Alzheimer's Disease, specifically the enhancement of amyloid beta-protein degradation.Strain Development
A transgenic construct containing the human membrane metallo-endopeptidase, MME, gene under the control of the mouse calcium/calmodulin-dependent protein kinase II alpha (Camk2a) promoter, and SV40 polyadenylation site sequence was injected into fertilized C57BL/6 mouse oocytes. The resulting chimeric animals were crossed to C57BL/6 mice, and are maintained on the C57BL/6 background.

Cryopreserved Embryos This strain is also available as cryopreserved embryos from our Repository. Orders for cryopreserved embryos are supplied subject to a signed agreement that must be returned to the Customer Service Department after order placement. Experienced technicians at The Jackson Laboratory have recovered frozen embryos of this strain successfully. We will provide you enough embryos to perform two embryo transfers. The Jackson Laboratory does not guarantee successful recovery at your facility. For complete information on purchasing embryos from our repository, please visit our Cryopreserved Embryos web page. Cryorecovery - Standard. The recovery process begins when a signed agreement form is returned to the Customer Service Department after order placement. Although results vary by strain, at least two males and two females (two pairs) will be provided, typically within 15 weeks of our receipt of the signed agreement form. If the first recovery attempt is unsuccessful or only one pair is recovered, a second recovery will be done, extending the delivery time to approximately 25 weeks. At least one member of each pair will be of known genotype and will carry the mutation if it is a mutant strain. Please note that pairs may not reflect the mating scheme utilized by The Jackson Laboratory prior to cryopreservation of the strain. Mating schemes are sometimes modified for successful cryopreservation. Price represents a repository maintenance fee, which includes the cost of recovery of the strain from the cryopreservation resource and the periodic replacement of the frozen embryos used for recovery. Cryorecovery to establish a Dedicated Supply for greater quantities of mice. |
