  • Contains a disruption of the H2-Ab1 gene
  • Expresses no A or E MHC class II molecules and therefore lacks most CD4+ T cells
  • Useful in transplantation, gene therapy and immunological disease research

Origin:

The Abb/B2m multiple targeted mutation model was generated through the mating of B2m and Abb lines from the Jaenisch laboratory at the Whitehead Institute and the Glimcher lab at Harvard University, respectively. Abb mice at three backcrosses (N3) onto C57BL/6 were mated to B2m at eight backcrosses (N8) onto C57BL/6 in 1992 by Laurie Glimcher. The mice were then backcrossed to N17. Taconic received stock through the NIAID repository and embryo transfer derived the line in 1996. The line is maintained through mating of double homozygotes.


Availability:

Occasionally, lack of interest forces us to discontinue live production of a Taconic Transgenic Model. Live production of this model ended in 2012. If you have a need for this model, please contact us to discuss available options.
