| Background | T cell receptor beta constant 1 (TRBC1) is a ~19 kDa protein. Constant region of T cell receptor (TR) beta chain. Alpha-beta T cell receptors are antigen specific receptors which are essential to the immune response and are present on the cell surface of T lymphocytes. Recognize peptide-major histocompatibility (MH) (pMH) complexes that are displayed by antigen presenting cells (APC), a prerequisite for efficient T cell adaptive immunity against pathogens. Binding of alpha-beta TR to pMH complex initiates TR-CD3 clustering on the cell surface and intracellular activation of LCK that phosphorylates the ITAM motifs of CD3G, CD3D, CD3E and CD247 enabling the recruitment of ZAP70. In turn, ZAP70 phosphorylates LAT, which recruits numerous signaling molecules to form the LAT signalosome. 1. Lefranc, MP. (2014) Frontiers in immunology 5, 22. PMID: 24600447 2. Rossjohn, J. et al.

SEC-HPLC detection for Anti-Human TRBC1 Antibody (Jovi-1).

Flow-cytometry using anti-human TRBC1 antibody. Human Jurkat cell line were stained with an irrelevant antibody (Green Histogram) or an anti-human TRBC1 antibody monoclonal antibody (Catalog # HP894107 , Red Histogram) at a concentration of 20 µg/ml for 30 mins at RT. After washing, bound antibody was detected using a CoraLite488 conjugated goat anti-mouse antibody (Catalog # MF690314) and cells analysed on a NovoCyte Flow Cytometer.
