TCR Vβ21.3 Antibody, anti-human, Biotin, REAfinity™

01MT08652

Clone REA894 recognizes the human β 21.3 subunit of the αβ T cell receptor (TCR Vβ21.3). The TCR is a disulfide-linked membrane-anchored heterodimeric protein 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 Vβ21.3 is a variant of the TCR β chain. αβ T cells express a diverse αβ TCR repertoire that specifically co-recognizes self or foreign antigen bound to antigen-presenting molecules, which thereby leads to T cell–mediated immunity. For example, the TCR can directly bind to peptide fragments, ri
