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

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 signaling^3,4. TCRα/β recognizes antigens bound to major histocompatibility complex (MHC) molecules, resulting in phosphorylation of CD3 ITAMs and subsequent T cell activation, proliferation, and survival^5,6.

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