Clone 500A2 recognizes an epitope on mouse CD3ε.

CD3ε is a 20kDa subunit of the TCR complex and is a transmembrane T-cell surface glycoprotein that belongs to the Ig superfamily. It is one of five polypeptide chains that form the TCR complex by associating with the CD3δ, γ and ζ chains, in addition to the TCR α/β or γ/δ chains. CD3 is involved in TCR signaling, enumeration of immunocompetent T-lymphocytes in peripheral blood, and signal transduction during antigen recognition.

CD3ε is primarily expressed on mature T cells and NK-T cells and at different levels on differentiation-dependent thymocytes.

Peptide antigen/MHC-complex.
