TCR beta

Next Day 2 - 8°C

TCRβ antibody, clone H57-597, recognizes the beta chain of the T cell receptor (TCRβ), expressed on αβ thymocytes and T lymphocytes, as well as natural killer T (NKT) cells1. TCRβ is a transmembrane protein that consists of an amino-terminal variable region, a constant region, and a stalk segment covalently linked to the TCR alpha chain (TCRα) via a disulfide bond2. TCRα/β does not contain signaling domains and is instead noncovalently associated with the CD3 complex (TCR-CD3), essential for TCR signaling3, 4. TCRα/β recognizes antigens bound to major histocompatibility complex (MHC) molecules, resulting in phosphorylation of CD3 ITAMs and subsequent T cell activation, proliferation, and survival5, 6.

Antigen recognition, T cell activation

TCR beta

Clone H57-597 recognizes an epitope on the constant region of mouse TCRβ. Clone H57-597 does not cross-react with γδ T cells.

0.5 mg/ml

TCRβ is expressed on αβ thymocytes, peripheral T cells, and NKT cells.

Each investigator should determine their own optimal working dilution for specific applications. See directions on lot specific datasheets, as information may periodically change.
