    Protocol

    Specificity / Sensitivity

    CD3ε (D7A6E™) XP® Rabbit mAb recognizes endogenous levels of total CD3ε protein. This antibody recognizes human CD3e protein and is also reactive with mouse CD3e; however, this antibody is not suggested for immunohistochemical analysis of mouse tissues. Monkey species reactivity is Immunohistochemistry (Paraffin) only.

    Species Reactivity:

    Human, Monkey

    Source / Purification

    Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Glu178 of human CD3ε protein.

    Background

    When T cells encounter antigens via the T cell receptor (TCR), information about the quantity and quality of antigens is relayed to the intracellular signal transduction machinery (1). This activation process depends mainly on CD3 (Cluster of Differentiation 3), a multiunit protein complex that directly associates with the TCR. CD3 is composed of four polypeptides: ζ, γ, ε, and δ. Each of these polypeptides contains at least one immunoreceptor tyrosine-based activation motif (ITAM) (2). Engagement of the TCR complex with foreign antigens induces tyrosine phosphorylation in the ITAM motifs and phosphorylated ITAMs function as docking sites for signaling molecules such as ZAP-70 and the p85 subunit of PI-3 kinase (3,4). TCR ligation also induces a conformational change in CD3ε, such that a proline region is exposed and then associates with the adaptor protein Nck (5).
