Specifications for TCR Vβ5.1 Antibody, anti-human, REAfinity™


Clone REA1062 recognizes the human variable beta 5.1 subunit of the α/β T cell receptor (TCR Vβ5.1), a member of the Ig superfamily. The TCR is a heterodimeric glycoprotein associated with the CD3 antigen. The α and β TCR chains are composed of constant and variable regions, each encoded by distinct gene segments. TCR Vβ5.1 is a variant of the TCR β chain. α/β T cells express a diverse α/β TCR repertoire that specifically co-recognizes self or foreign antigen bound to antigen-presenting molecules, which thereby leads to T cell–mediated immunity. REA1062 does not recognize Vβ5.2 or Vβ5.3.
Additional information: Clone REA1062 displays negligible binding to Fc receptors.
