Tau - Model 1638

Random Transgenic

Tau (Model 1638) Random Transgenic Mouse Model
Taconic no longer produces line #1638, which was the hemizygous version of the Tau model (this line also produced wild type controls). Taconic continues to produce line #2508, which is the homozygous version of the Tau model. This webpage is maintained for historical reference.

Genetic Background:

C57BL/6, DBA/2, SW Mixed Background


The Tau mouse was developed in the laboratory of Mike Hutton at the Mayo Clinic. The model was created by microinjecting transgenic constructs containing the P301L mutation of the microtubule associated tau gene and mouse prion promoter into B6D2F1 x SW zygotes. The resultant mice from Founder Line JNPL3 were mated to B6D2F1. Taconic received stock in December 2000. The mice were derived by embryo transfer and mated to SW and B6D2F1 hybrids and embryo transfer derived. Offspring from both backgrounds were combined and were mated to B6D2F1 mice to produce hemizygous and wild type mice (1638). Hemizygous Tau mice were intercrossed to generate homozygous Tau mice (2508). The homozygous colony is maintained by incrossing homozygotes.


Wild type for Nnt mutation; carries Pde6brd1 mutation
