Description | Specificity: Chicken/Turkey/Peacock/Guinea Fowl TCRalphabeta/V beta1; Mr 50& 40 kDa. MAb TCR2 precipitates a CD3-associated heterodimer of Mr 90-kDa (two bands of Mr 40-kDa and 50- kDa upon reduction) on chicken peripheral blood T cells.1 Deglycosylation of the heterodimer yields two polypeptides of Mr 34-kDa and 29-kDa from TCR2 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 TCR3,1-3 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.4 The TCR2 MAb reacts with approximately 40% |
