TCR Delta
Use
T‑cell receptor delta (TCR delta) is used as a phenotypic marker for TCR delta‑expressing T‑cells. TCR is a heterodimer composed of either alpha/beta or gamma/delta. TCR delta is expressed by thymocytes and a majority of peripheral (gamma/delta TCR‑bearing) T‑cells. Evaluation may help in the differential diagnosis of T‑cell lymphomas.
