Biolegend, 127817, APC/Cyanine7 anti-mouse TCR Vα2 Antibody, 25μg

The TCR alpha (α) chain complexes with the TCR beta (β) chain to form the T cell receptor in 95% of T cells, whereas the remaining 5% of T cells express gamma and delta chains (γ/δ).  TCR Vα2 is a distinct TCR subfamily found in mice having the a, b, and c haplotypes.
25μg
