Biolegend, 139512, APC/Fire™ 750 anti-mouse TCR Vβ5.1, 5.2 Antibody, 100μg

Vβ5.1 and 5.2 T cell receptor (TCR Vβ5.1, 5.2) are variants of TCR β chain that, along with TCR α chain, forms the TCR heterodimer. In association with the CD3 complex, TCR α/β is responsible for antigen recognition in the MHC-Peptide complex and the initiation of T cell-mediated immune responses.
