Description | Specificity: Chicken TCR V alpha beta (V beta 2). MAb TCR3 precipitates a CD3-associated heterodimer of Mr 88-kDa (two bands of Mr 48-kDa and 40- kDa upon reduction) on chicken peripheral blood T cells.1,2 Deglycosylation of the heterodimer yields two polypeptides of Mr 34-kDa and 31-kDa from TCR3 precipitates. In the chicken, two distinct subpopulations of alpha beta T cells appear in the thymus subsequent to the appearance of gamma delta T cells. These subpopulations, originally denoted as TCR2 and TCR3,1,2 arise sequentially in the thymus during ontogeny and are now known to represent two distinct V beta families, V beta 1 and V beta 2, respectively.3 The TCR3 MAb reacts with approximately 9% of thymocytes, 15-25% of blood mononuclear ce |
