A third sublineage of avian T cells can be identified with a T cell receptor-3-specific antibody.

Abstract excerpt

Avian homologues of mammalian gamma delta and alpha beta TCR, termed TCR1 and TCR2, have been identified in the chicken with specific mAb. A third TCR, dubbed TCR3, has been identified on a subpopulation of T cells that lack the TCR1 or TCR2 epitopes. We have now produced a mAb that identifies this TCR3 molecule. The anti-TCR3 antibody immunoprecipitates a CD3-associated heterodimer with a relative Mr of 88,000,...
