TCR, alpha, beta, V beta 1 (T Cell Receptor)

Cat no: T2040-02V

TCR, alpha, beta, V beta 1 (T Cell Receptor)

This antibody precipitates a CD3-associated heterodimer of Mr 90kD (two bands of Mr 40kD and 50kD upon reduction) on chicken peripheral blood T cells.1 Deglycosylation of the heterodimer yields two polypeptides of Mr 34kD and 29kD from antibody 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 Vbeta families, Vb1 and Vb2, respectively.4 Two-color immunofluorescence has revealed that most of the TCR2+ thymocytes express both CD4 and CD8 antigens. The TCR2+ cells in blood were found to express either CD4 (74
