CST, 77046S, TRBC1/TCR beta constant region 1 Antibody

Polyclonal Antibody for studying TCRbeta. Validated for Western Blotting. Highly specific and rigorously validated in-house, TRBC1/TCR beta constant region 1 Antibody (CST #77046) is ready to ship. Product Usage Information Western Blotting: 1:1000 Storage Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at -20°C. Do not aliquot the antibody. Protocol Available protocols: Western Blotting Specificity / Sensitivity TRBC1/TCR beta constant region 1 Antibody recognizes endogenous levels of total TRBC1/TCRβ constant region 1 protein. This antibody does not cross-react with TRBC2/TCRβ constant region 2 protein. Species Reactivity: Human Source / Purification Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues near the amino terminus of human TRBC1/TCRβ constant region 1 protein. Antibodies are purified by peptide affinity chromatography. Background The αβ T Cell Receptor (TCR) is a heterodimer composed of an alpha chain and a beta chain expressed on the surface of T cells (1,2). It detects peptide antigen presented by major histocompatibility complex (MHC) molecules (1,2). Detection of cognate antigen leads to activation of the TCR signaling pathway through the CD3 signaling chains that associate with the TCR (1). The TCR chains are made up of a constant region and variable regions that get rearranged during T cell development in the thymus (3). There are two TCRβ constant genes, and (3). A population of normal T cells is polyclonal and contains a mix of TRBC1- and TRBC2-expressing T cells, while T cell malignancies are monoclonal and all express the same TCR which either contains TRBC1 or TRBC2 (4). Therefore, it is possible that T cell malignancies could be identified and targeted with reagents or therapies that can distinguish between TRBC1 and TRBC2 (4).
