Gene Information

Transgene: Tg(APPSwLon)96Btla [MGI:3693359] (Mus musculus (mouse))
Name: transgene insertion 96, Bruce Lamb
Synonyms: J1.96, K670N/M671L + V717I, APPK670N/M671L and APPV717Im, Tg(APP*Swe*Lon)96Btla
Chromosome: unknown
Alteration at locus: Transgenic
ES Cell Line
J1 derived from 129S4/SvJae
Homozygous: Homozygote phenotype is expected to be similar to hemizygote phenotype.
Hemizygous: Mice hemizygous for this "K670N/M671L + V717I" mutant APP YAC transgene are viable and fertile. RT-PCR analysis shows hemizygous mice express the mutant human APP mRNA at levels similar to endogenous mouse in brain and peripheral tissues. Further, transcript levels of the most common alternative splice variants (encoding human APP-695, -751 and -770) parallel the endogenous mouse gene expression. The levels of total amyloid-beta and longer amyloid-beta peptides (species terminating at amino acids 42/43) are elevated compared to wild-type mice, but not to the extent as observed in a similar strain carrying only the APP (K670N/M671L) mutant transgene. These mice may be useful in studies of the pathogenesis of Familial Alzheimer?s Disease, specifically focusing on the importance of processing at the gamma-secretase site to elevate levels of amyloid-beta 1-42(43).

Strain Development
A 650 kb YAC transgene containing the entire human amyloid beta (A4) precursor protein (APP) gene, and approximately 250 kb of flanking sequence, was altered to include the Swiss mutation (K670N/M671L) and the London mutation (V717I) associated with Familial Alzheimer's Disease (FAD). This construct was injected into 129S4/SvJae-derived J1 embryonic stem (ES) cells. Founder animals (line J1.96) were found to contain a single copy of this mutant human APP YAC transgene. These mutants were backcrossed to C57BL/6 for at least 11 generations prior to arrival at The Repository.

Colony and Husbandry Information

When maintaining a live colony, mice are bred by homozygous intercross.
Mice recovered from a cryo-archive will have health surveillance performed on recipient females. Health reports will be provided prior to shipment. If you require additional health status information, please email .

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.

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 and based on the transfer success rate of the MMRRC facility) to transfer to at least two recipients. The MMRRC makes no guarantee concerning embryo transfer success experienced in the recipient investigator's laboratory. Neither gender nor genotype ratios are guaranteed.
