The Transgenic DO11.10 T Cell Receptor mouse was generated by Dr. Ken Murphy in the Laboratory of Dr. Dennis Loh at Washington University, St. Louis in 1989. The line was made with the rearranged Vb 8.1 and Va 13 T cell receptor genes of the Kappler and Marrack OVA-specific T cell hybridoma DO11.10 using (C57BL/6 x C3H/HeJ)F1 x BALB/c donor embryos. The founder line has two copies of the Vα gene and four copies of the Vβ gene cointegrated onto the distal part of chromosome 18. It was initially backcrossed to BALB/c 12 times. The line was then transferred to Dr. Ethan Shevach at NIH and subsequently embryo transferred into the NIAID Repository at Taconic. The N12 mice were crossed twice to a homozygous Rag2 knockout mouse on a BALB/cAnTac background and Rag2-/-, DO11.10 positive offspring were selected. These mice were then intracrossed to produce the line homozygous for the TCR transgene. TCR homozygotes were selected by test mating the mice to wild type partners and identifying the animals that only gave rise to transgene positive offspring. This strain is designated as N14.
