C57BL/6 CD3+ splenocytes stained
with H57-597 PE and TCRγ/δ (UC7-
13D5) FITC
Description:
T cell receptor (TCR) is a heterodimer consisting of an α and a β chain (TCR α/β) or a γ and a δ chain (TCR γ/δ). TCR-β is a member of the immunoglobulin superfamily and a component of the CD3/TCR complex (along with TCR-α). It is expressed on α/β TCR-bearing T cells and thymocytes. The CD3/TCR complex plays a key role in antigen recognition, signal transduction, and T cell activation. The H57-597 antibody does not cross-react with γ/δ TCR-bearing T cells. Immobilized or soluble H57-597 antibody can activate α/β TCR-bearing T cells.
Other Names:
TCR-β chain, TCR-β, β-TCR
Structure:
Ig superfamily, CD3/TCR complex with CD3 and TCR α subunit
Distribution:
Majority of T cells and thymocytes (correlated to differentiation)
Function:
Antigen recognition, T cell activation
Ligand Receptor:
Peptide bound-MHC class I and II
