Description

These mice express a transgene containing a rearranged genomic segment derived from the Tcrb locus.

Detailed description

This transgenic mouse was constructed with a rearranged genomic segment derived from the Tcrb locus. T lymphocytes express the transgenic TCRB chain on cell surfaces while the protein products encoded by endogenous Tcrb genes are not expressed. Homozygous mice generally don't survive beyond postnatal week four. This strain may provide a specific developmental marker for a prothymocyte lineage subset that lacks pluripotential properties.

Development

The Tcrb genomic segment was constructed from B6 (Tcrb-V8.2,Tcrb-D) and BALB/c (Tcrb-J, Tcrb-C) sequences. The construct was injected into pronuclei from CBA/BrA X C57BL/LiA (F1)mice. To establish the line, a male founder was mated to a female C57L.

Molecular note: The transgene contains a rearranged genomic segment derived from the Tcrb locus, and was constructed from B6 (Tcrb-V8.2,Tcrb-D) and BALB/c (Tcrb-J, Tcrb-C) sequences. Over 98% of T cells express the transgenic TCR-beta chain in hemizygous mice. The rearranged beta-chain sequence was isolated from an anti-H-Y, H-2D^b-restricted CD8⁺ T cell clone, B6.2.16.
General note: In transgenic mice, T lymphocytes express the transgene on cell surfaces while the protein products encoded by endogenous Tcrb genes are not expressed. Most homozygous transgenic mice do not survive beyond postnatal week four.
