The α/β T-cell receptor (TCR) recognizes a peptide bound to MHC leading to T cell activation. α/β TCR expressing T cells comprise more than 90% of CD3+ T cells in peripheral blood. The clone QA20B12 antibody only reacts with the α/β TCR, not the γ/δ TCR.

- 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 5 µL per million cells in 100 µL staining volume or 5 µL per 100 µL of whole blood. It is recommended that the reagent be titrated for optimal performance for each application.
