Genotype Determination

Homozygous: Not evaluated.

Heterozygous: The E391- 3608 line express E391-truncated -4R-tau, at levels that approximate those of endogenous mouse tau. The 3608 line shows lower expression than the 3610 mouse line, although it contains the same transgene. Despite lower tau expression levels, pre-tangle pathological changes in tau were observed in the 3608 mouse line to a greater extent than in the 3610 line. Both lines exhibited atypical neurites as detected by staining of antibodies to tau. Mice of the 3608 line additionally exhibited irregularly shaped dystrophic neurites with abnormal orientation to the cortical surface, similar to dystrophic neurites observed in AD. Pyramidal neurons in the cortex of 3608 mice often appeared irregular, with thickened, atypical apical dentrites. Despite these pathological changes frank tangles did not develop even though mice were aged to 2 years.

Colony and Husbandry Information

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 .
Coat Color
MMRRC Breeding System
Breeding Scheme(s)

The mice that are hemizygous for the transgene and homozygous for the targeted mutation (Mouse tau KO/KO) are mated to siblings that are transgene negative and homozygous for the targeted mutation. The mice have no unusual breeding characteristics.

Overall Breeding Performance
Viability and Fertility: Female Male Comments
Homozygotes are viable: Unknown Unknown
Homozygotes are fertile: Unknown Unknown
Heterozygotes are fertile: Yes Yes

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 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.
