FC - Quality tested

Application Notes:

The B20.1 antibody recognizes most members of the Vα2 TCR subfamily in mice having the a, b, and c haplotypes.

Recommended Usage:

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.25 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

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.

Other Names: T cell receptor Vα 2
Distribution: On a subset of T cells
Function: In combination of V β, Vα recognizes MHC/peptide complex on the antigen-presenting cells.
Ligand Receptor: TCR recognizes MHC/peptide complex
Interaction: Associate with Vβ and CD3 complex to form TCR complexes expressing on cell surface.
